And if DMs had a word on that, ToB and Psionics would never have been printed >.>
I do not understand what Tome of Battle has to do with it. Please enlighten me in a non-condescending manner.
I'm never condescending. It's called censorship, what I typed up before submission is worse.
ToB is banned in more games than 3.0 content according to the threads here asking for help. And Psionics has a terrible (correct) conception of being broken as all get out and so it commonly gets banned too. So if your DM had a word on what was or wasn't allowed on the forums then Psionics and ToB would be nixed far sooner than 3.0 content.
The broken stuff in 3.0 could probably be counted on one hand. Really. Just pick up your copy of BoED and read about the Starmantle Cloak and Amulet of Retribution then skim the pages of Exemplars of Evil for Friendly Fire to learn how to ignore being attacked. Even the three mentioned classes for immunity to damage (bone knight, pale master, crimson scourge) are found in 3.5 books. A good kicker is the broken as hell Incantatrix which was originally printed in the 3.0 rule set is officially a 3.5 based class thanks to it getting a reprint.

Iaijutsu Focus is capped at 9d6 damage (barring use of epic rules) and that is assuming you are reliably making a DC 50 skill check every single time you attack. In total that is +31.5 damage. On the other hand a Swordsage can stance up +2d6 SA and pick up both Craven and a CL 18 Wand of Hunter's Eye. For a much lower DC 20 check he has +8d6+20 or +48 and it is
not a Sneak Attack based build and woe betide you if you want to bring up charging. Heck, even a Warlock deals more than Factotums with Iaijutsu Focus.
