If you have to rely on the argument you can't do "whatever" in real life, well, D&D (3.5) is not designed well-enough to make that argument feasible.
Sorry, but I think D&D in general try very, very hard to be as close to reality than possible without cutting down on the fun factor and succeed very well at it. We're not discussing magic or any intangible force here, we're discussing being able to layer different kind of armors in the hope to add up on the defense factor.
True our current talking point is layering a (quite possibly magical) "light" "armor" underneath a (quite possibly magical) heavier (and rigid) "medium" or "heavy" "armor". Note the air quotes? Thats because in normal conversation those words are relative to context and the context here is the table of Armor and Shields in the PHB. Which states that a chain shirt weighs in at 25 pounds and that a Breastplate weighs in at 30 pounds. So thats 55 pounds... must be way to heavy to move in right? Well Full Plate weighs in at 50 pounds so unless those 5 pounds broke the camel's back ( ok stupid turn of phrase there) you can still RUN at 3x your landspeed.... thats an 8 second 40 yard dash wearing 50 pounds of rigid articulated metal or 55 pounds of metal on top of (well i guess its quilted padding) on top of a "chain shirt" ( i guess thats a "mail" or "maile" shirt)
So I guess its up if you think that meets "realism" I haven't ever had the opportunity to do speed drills with metal armor on.
I remember reading some very good papers about realism in D&D. I remember one in particular which suggested that the max level someone in the real world could be in comparison to D&D around level 5. So take about any best of the best person or worker or whatever in the real life, in D&D they would be about level 5. Great stuff to read and it really help to imagine realism in relation to real world in this game.
You wouldn't happen to remember how I might find that would you? I'd actually love to read it, as I'm going to be doing a panel about D&D vs Real Life (or more precisely physical skills and combat) next year at MomoCon (shameless plug: come to the convention!)
Comparing what people can do in real life version D&D is counting on skills though. Stats are another different thing altogether. I have PCs with a strength score of 18 in my games and I would not say that even them would be able to lift a real anvil above their head and throw it efficiently. Not a human or a dwarf anyways. A monstrous entity maybe...
That or we don't have the same definition of an anvil, I guess. Maybe you have very, very small anvils in your world.
Now about the anvil, well i was worried that I had spoken too soon, but I did a a little bit of searching and found a reference that gives general weights for various types of anvils. The heaviest two types of anvils are forging and farrier anvils IRL, but I couldn't find a reference to anvils in the srd ( and unfortunately I don't have AEG around) so we'll go with the IRL numbers. A forging anvil goes from 75 to 500 pounds which means (based on which size anvil) a strength 10 character could lift the smallest one above the head and a strength 22 character could lift the heaviest one above their head. Note that a strength 22 character can (if wearing less than 20 pounds of other gear) according to the text after that carrying capacity table can
"hoist [anvil] over onto his shoulders, and now the [character] is carrying [500] pounds. He can manage it but it's a heavy load. His [blah Dexterity, AC , armor check yada yada] ..., and now he runs at x3 speed instead of x4.
Which means again if his standard landspeed is 30 ft a round then its an 8 second 40 yard dash while carrying a 500 pound anvil on his shoulders.
I would contend that the D&D authors worked towards ( perhaps some would say blindly groped towards) internal consistency and referenced real experience in some of the places that simulated fantasy game and real life experience could intersect but I won't say the authors got to "realism".
I'd like to point out that while LARPing is awesome its not D&D and the thought you just expressed specifically leads to "melee" can't have nice things.
Thank you for the LARP compliment but that really wasn't the point I was trying to make. Also, I really don't understand how preventing melee chars to layer armor simply to stack bonuses lead to melee can't have nice things.
Let's not forget that the main point of this thread is "I think I found out an interesting way to get armor enhancements +10 more cheaply than before", which in itself is not a way to get "nice things" but rather some try to break and abuse the system in place. There is rules and this suggestion is clearly trying to circumvent them. I am not surprised to see people stepping and answering just plain no...
I read the OP to be saying that "there is a rule here that says one thing about armor, an object that is named shirt over here without an exception rule, and another rule talking about things named shirt over here" its a rules wormhole that loops back into itself.
As for "melee" can't have nice things well I still haven't come up with a really a better term because I refuse to perpetuate the idea that somebody who can run a 40 yard dash in 8 seconds in a loin cloth,carrying guisarme in one hand and an anvil in the other is
mundane.
The issue is anything that isn't magic has intersection with the in-game representation of "real world" physics. I.e. the charts for ability scores reflecting how much you can carry, how fast you can run etc and the skills list that don't have to do with "soft sciences" and "magic" ( so not things like diplomacy or spellcraft) but stuff like jump, balance, and climb. I read a scenario the other day about somebody need adjudication on "my swashbuckler wants to jump off a balcony, grab a silk rope, swing towards someone below me and attack as if i'm charging". Somebody came up with like 6 skill checks for that and there was an argument about if it counted as charging... Guess what though? One freaking spell can make that whole adjudication moot... "My gish casts fly the round before, i then do a charge (flying blithely through the air of course) and skewer the bad guy."
I'm just trying to say that taken as a whole the idea that you want to be "realistic" because you have some way of working through game construct <-> real world equivalence means you get to do way less ( or have to succeed more d20 rolls to try) than what people get to say when they cast spells. Which by the way "Hey its freakin' magic! It does exactly what the book says it does! Now gimme my Decanter of Endless Water powered hover donkey!"
