I am a great admirer of Frank and K's theory, which is correct almost every time. While I don't agree with many of their solutions, I cannot claim that they do not work.
I really love thier work, I argued with them a lot when I first got online, about fighters and fixes and one day K was like: Okay you know what you know, about the game but please just take a second, and reexamine what you know cause basically right now your arugment is "uh-uuuhh". Or something to that effect, I stopped listend read thier work and was suitably humbled. I went back and made a post thanking them at the den. It set me to optimizing properly really.
I think we can learn a lot from the work they've done, mostly in the sense of what Omen of Peace said.
The did a really good job of showing how absurd everything is/can be. So it easier to say "yes frank and K are right but lets change the bad things and make everything resonable," since we're just coming up with perfect houserules anyway.
Do you guys rember Szatany? The Ulitmate class makers? He did a huge body of work theres a wiki of it.
One thing I like about all this is that we have a stated goal of Tier 3. So we have great examples of what were shooting for
. Beguiler, Dread Necromancer, Crusader, Bard, Swordsage, Binder (without access to the summon monster vestige), Wildshape Varient Ranger, Duskblade, Factorum, Warblade
So we have less dissension, F&K balanced for tier 1.
Paizo just had a marketing strategy and a few *okay* ideas.
We... we just have so much great work to draw on.
From OwA Paladin to Starlights work, we're going to end up with a really excellent system in the end. IMHO.
