But plenty of games have dealt with debuffing bosses. It's just plain stupid the devs included some debuffs in the game that are worthless. I don't even have feint on my DRG's hotbar because it barely affects anything, it's so beyond situational it's just a waste of space for something more useful.

Slow I think is a perfect example, they could make bosses susceptible to slow and maybe just make it cap out at a %, so instead of 20% they only get hit with 7%, it's not so overpowered but still adds something and makes classes with that debuff actually able to use it.

Debuffs aren't over powered, you just need to learn to maths. Besides there's already an MMO out there that handled debuffs well, it's called FFXI, I'm sure the devs heard of this obscure and highly foreign game.
