I'll disagree with this on one point.
ToB: Book of 9 Swords actually fixed the horribly underpowered martial characters in 3e. Was it a power boost for melee types? Yes, but only to bring them in line with the hideously overpowered casters which dominated before.
See, I know that was a very common complaint about pre-4e versions, but it just wasn't my experience at all. Even now, in my 7th level Eberron game, the Rogue is holding his own when in a party with a Wizard, a Psion, a Druid, and an Artificer.
I think part of that is that we mostly played "Core Rules Only", which meant that the spellcasters (especially divine casters) didn't get the absurd levels of power-up that came from every new book containing new and more power spells (and metamagic) for them. I think part of it may well just be that my spellcasters have never been played to their fullest - the artificer in the current campaign is the first time I've seen a player
really work to maximise his character. And I think part of it may be that we stuck pretty solidly to the Wealth by Level guidelines, which seems to help non-spellcasters considerably more than casters.
But I think a very large part of it is that our playstyle doesn't really allow the 15-minute Adventuring Day. And no 15m-A-D means that the casters can't "go nova" to anything like the same extent, which vastly mitigates their power.
The upshot of this is that the only* time I really saw a character totally dominate the game was when I allowed Bo9S and one player took a Crusader.
(* Okay, that's not
strictly true. I once played in a Ravenloft game where one player "rolled" 18/18/18/18/14/10 for his character's stats, and proceeded to dominate the game. But I'm sure you'll agree that was a special case!)
My other big objection to Bo9S, though, was that the classes weren't just unbalanced next to the PHB martial classes - they were unbalanced next to
each other (where I believe it was the Crusader that was the worst offender). That book was one of the test-beds for ideas that would later show up in 4e, and it really shows - it's almost as if the designers had their minds on some other, bigger project...
It's a shame. I actually really like the concept of Bo9S, and would love to combine it with the "Expanded Psionics Handbook" and "Oriental Adventures" to do a "Crouching Tiger"-like campaign.
(And with that, I'll try to stop derailing this thread with 3e-talk. Sorry.)
