I prefer solo content and leveling toons, playing none for the toughest group content (m+, raids, pvp). I like how the different classes have differing playstyles to obtain the unifying goal of oblitering mobs.
But, omg, devastation evoker is the most squishy of everything I have played (I have all classes at max level). Because I play all classes, I likely suck at one or more or all of them. Devoker is the only class, however, that I have died to prey bosses after getting some gear.
My 270+ devoker still dies to some prey bosses that spam spells. I just run out of interrupts/defensives, and their spells rot me down. Other open world content and t11 delves remain easy. Heck, getting to the prey bosses is easy mode even with ambushes, echos, and kill-me-now all happening at once to my devoker.
I really, really enjoy the drachthyr aesthetic and devoker playstyle. (My dragon body, my choice.) But skill issue?
