WAR have to keep a constant eye on infuriate to gain the most amount of time reduction for the skill, WAR have to focus on use his oGCD on inner release to maximum damage, WAR have to manage his gauge and avoid using infuriate under inner release bcs is a massive dps lose, WAR have to manage a lot of stuff and his mechanics at contrary to DRK ones have sinethy and you have to pay attention to many stuff, I don't say is hard bcd that's relative.
but ppl should stop saying DRK is more harder when you don't manage actually anything with the job, 1 mindless combo, 1 mindless spam window without worry about anything except land 5 bloodspillers, build MP and just throw it all on bloodweapon as avoiding overcap with is the most easy thing bcs you barely gain MP over the downtime.

Let's stop playing the card of my job is harder should be? All jobs are literally the same, WAR is just more boring (relative) not easy.
