The "center options" are ok, but "hard" and "unfair" are still insane. The strengthened enemies have some mad AC, saves & CMD. You can still choose to pick "hard" but lower the enemy stats in the options if stat bloat is what bothers you the most.
I am playing a hunter trickster, acrobatics variant, and the CMD of most of the enemies even with a Mythic trickster is impassable in Hard mode.
PD: I still love tricksters, btw. The trickster path is hillarious.
