Tl;dr devastation needs a lot of help in M+ both defensively and offensively. It lacks a niche and doesn’t really serve any purpose in a group comp that can’t be better served by other specs.
Season 1 has been an absolute disaster for this spec mostly because of augmentation existing, amongst many other things. Devastation is in need of some series help on many fronts if you’re want to push keys semi-competatively alongside aug. As much as I enjoy both aug and dev, having it be so one-sided doesn’t sit well with me. Even after recent aug nerfs, the spec is still miles ahead of dev and its not even close.
Defensively, even when played well, it is very weak and can often fall over with no answers to your problems. Self healing is among the weakest of all the hybrid specs. High keys with constant rot damage is difficult to deal with and a lot of times praying someone has an external or the healer has cooldowns.
Offensively its average at best and doesn’t excell at anything that other specs can’t do better. Single target is below average outside of cooldowns and even with cooldowns its roughly average at best. It also completely lacks priority damage, making it even less desirable for comps.
Ever since the prepatch, dev evoker has lost its niche with big bursty AoE damage due to the many Consume Flame nerfs time after time. Prior to the consume flame nerf, I was completing up to +23 keys over the prepatch period and even reached #1 in the NA region for the spec because of that (yes I know its prepatch and it doesn’t matter in the slightest, but I wanted to mention this to point out the significance of these nerfs). Scalecommander deep breath can cover the bursty AoE somewhat, but is nowhere near as potent and puts you in a risky position more often then not. Other times you can’t even use deep breath without risking killing your team (2nd boss of skyreach for example). Yes its possible, but again, very risky. It does have the saving grace that you can cheese some mechanics.
I feel that to push dev in the right direction, it would need three things: increased defensiveness via an extra button and/or better self healing, damage in general to be improved outside of disintigrate on both the single target and AoE front, and something that helps the spec deal some amount priority damage outside of borrowed power. Also tip the scales is borderline useless for both dev specs. It basically functions as a method to extend rage longer and has to be used on eternity surge specifically. Using it on firebreath is a dps loss due to how catalyze and consume flame works.
I love this game and I love playing evoker. I would love to see dev shine alongside aug in the best case scenario, but we all know that will never happen. All I ask is for SOME kind of help. And no a 5% aura damage boost won’t fix the problem. The hero talents and how they play is what needs help. Give us some kind of niche we can fulfill, because right now we’ve got nothing.
