TWF fighter is either a "light" fighter by definition. If you have evasion, you must wear light armor. If you do not have evasion, all of the "ultimate" (epic chain, epic dragonscale) things are light. There really is not a reason to wear heavy armor unless it has some awesome effect on it.
Rangers arent really "gutted", but they do get 15% or so less DPS than fighters.
Evasion thing- no
I want my rogue to get barb rages and lots of temporary hitpoitns
I want my barbarian to be able to manyshot and bowstrength
I want my wizard to get free evasion with no splash
difference between want and game balance, classes do what they should do, and no part of fighter is "dodging spells and traps completely"
