(Pathfinder) Path of War: How is it?
So, unless you play E6 or E11 style ( or whatever variant ) you will always have the fabled "Linear Fighters, Quadratic Wizards" equation.
With E#, you can prevent it by simply never reaching those insane levels. (Not sure if you're familiar with the idea - essentially, characters stop leveling at a designated level, such as 6 - a point where fighters are still able to take-on wizards to a degree, but, wizards still have a lot of "one-encounter" power.)
That being said - yes, Path of War and the Unchained books do offer a lot of neat stuff for fighters and rogues, however; only the most munchkined of character builds will ever compete with a vanilla wizard, or *shudder* a summoner.
