um, I have read the prd...and I do not see even close to an equal footing with a 12th level fighter or a 12th level wizard...
spells still go up way fasster then anything else, and fighters still do not have options to match.
had they gone more of a Bo9S route maybe...but as it stands now the fighter is no better at above 8th level in path finder then he is in 3.5 (Yes they increased him, but they increased the mage too...I have said it before and I will say it again..."Who sat there at a pf meeting and said "We need to give wizards MORE class features...you knw even though they are one of the top 3 classes"))
Edit: please I beg of you to prove me wrong...I would like nothing more then to come back here and find a fighter power/feat/option on par with a 6th level spell...
