Its definetly doesn't feel good in low keys and is a c tier class in M+ for the most part. You generally start with seed to get corruption on everything, get 3 to 5 agonys out, if you have time get a UA on a target, if not get vile taint up as well and start ripping raptures.

Its feeling like a lot of work that isn't really worth it. My MM just drops wild spirits and barrage go brr brr. Now its pretty strong in raid and since M+ EOD gear is gonna be obsolete for me in a few more weeks I probably won't be doing many keys so it is what it is.

I personally miss legion affliction, just throw seeds and watch things explode. It kept up at lower levels much better and was extremely strong in high keys too.
