Doesn't Fighter get Dungeoncrasher, Overpowering Attack, Zhentarim Fighter Subs (and thus makes for a decent Intimidator with Imperious Command; thanks to not needing Wis, Fighter can actually afford it too), less attribute dependancy (no need for Wis), better Will-saves (thanks to Resolute), more skillpoints for...say Knowledge Devotion (Thug) and earlier access to worthwhile feats (Shock Trooper, Robilar's Gambit) though? I mean, I'm not saying Fighter comes out ahead, but to say that Fighter has nothing on Psy War is pretty dumb.
Dungeoncrasher certainly enables builds Psy War simply cannot try, Zhentarim Fighter Subs allow Fighter to actually make for a decent Intimidator, Knowledge Devotion + RWM are actually relevant as far as archery goes (good luck getting 6 Knowledges maxed as Psy War), etc.
