I have played a lot of hours on Deva and on other classes and ratings between 2.4-2.8k in 3s this season.
Devastation to me is 100% the weakest of the caster classes only being Augmentation. I think the list of cons greatly outweighs the pros of this spec
Pros
-Great DMG output if left alone
-Low CD defensives
-Great damage output if left unchecked
Cons
-Very little to no control over your target
-Best damaging spell is a chanel
-Fake casting Disintegrate is pointless. If you juke with it you still lose the ability and without the essence to do another one you are still doing 0 dmg
-Sleep walk is Evoker’s best CC…it is dispelable and has a CD
-If rooted you cannot use half your defensives. You cannot rescue someone in a root or if you are rooted and you cannot verdant while rooted. With a 25 yard range this is really really lame
If Evoker’s main design is to be a damage bot then you really need to give them a better kit to be a damage bot. I suggest a few quality of life changes
-Make disintegrate unkickable
I know this sounds rough to face but this spell is literally the only thing a Devastation has outside of their super purge. They made Eye Beam unkickable since it is a channel and due to the fact that when using it you should always be within kick range. TThe best way to counter Deva is to just stop disen. This is the main reason you see very very few high rated Deva Evokers. They are far to easy to shut down
-Make rescue breaks on both targets…honestly do not know why this is not a thing already
-Make hover last longer for Devastation evoker. The class is designed to be constantly mobile. No matter what there should never be any down time on hover
-
Remove Obsidian Mettle if you make Disintegrate un kick able
-
Remove CD on sleep walk and remove Dream Walker
-Lower PVP damage on Disintegrate. With it being unkickable the ability may become too powerful
-Buff azure strike and living flame damage for Deva.
-Give Deva Blistering Scales.
Currently Deva just brings nothing to the table other than some solid burst damage. But any team with a brain will know how to counter it. Deva is practically a melee class with a 25 yard range restriction. Ports/blinks,Dashes, coils, stuns and every small cc can break or cancel disen. With the current design it would be really nice to not have to deal with kicks for it at least
