Arena matches will never be fair.
Perfect fairness doesn't exist and I never said that's what I'm going for. If you'll notice, I said it's an in-character thing, not a metagame thing.
They favor single target affecting stuff generally
Well, then you'd better have that if you want to win.
give much greater importance to ability to play up a crowd w/ perform (weapon drill) than real life struggles of course (you do use that, right?)
No, I don't. This isn't a spectacle. More like a tournament.
policy on use or banning of expendable items will favor some over others
If you rely on magic items too much, you're not really fit for arena combat.
and any amount of prep rounds for buffing or allowing to walk into the match pre-buffed will inherently help or disenfranchise one person or another (two rounds to buff does diddly squat for a Fighter, but a gish would love it)
There's no pre-buffing.
Plus, any attempt to let primarily mage types battle primarily fighter types will inevitably end in tears and bitterness.
I'm aware. I'm slowly working on it.
I'm of the opinion that pets and minions *shouldn't* be allowed in an arena match, unless both people have one and want them included.
And I'm of the opinion that if the guy without an ally wanted one, he should have gotten one. But he didn't. He choose a different path.
Arena will never accommodate every build equally, and the reason you're having a hard time finding a good justification to allow one side to outnumber the other -- but only in these specific ways and certainly not by means of any of those ways! -- is because there is no such thing.
Uhm, Ketaro already provided a good answer for my inquiry.
You're giving one side a blatant advantage in action economy, probably about double the actions of the other side. It looks unfair because it is unfair.
Except that's not the type of fairness we are talking about.
This thread served it's purpose. Thanks to all of you for help.
Stream, if you want we can continue this friendly conversation, maybe it'll help me with my work on this arena game, but honestly I'm not that interested in arguing.
