Yes... maybe instead of giving a shard, killing a target with DS should double the damage of your next UA. And still it will be garbage in M+!
Affliction just doesn't have time to shine. It has standard damage scaling potential - dot's are just doing X damage per target, PS is doing X per target - linear scaling.
Other specs who are wanted in M+ are scaling exponentially, no wonder Aff is shit.
I'm playing both mage and warlock this tier - I don't trust the community to be open for Warlock dps - even tho they have the 2 min cd to work around - just like mages. Not a big difference tbh. But often get treated like we have aids, just being Warlocks T.T
