We are salty because our main raiding spec suffers debatable degradations through this change.
If the talent goes live it in the current iteration this is already sim'ed to be a ~100k dps loss in mythic gear.
That's enough to feel annoyed to say the least.
While not exactly great, assassination serves some purpose in raids. The single target DPS is good and rogues can provide sponge/ soaking service when needed.
Outlaw has decent cleave but subpar single target.
Sub is only half assed at both.
That leaves you with
one spec (out of three, as a dps class mind you) which currently had some appeal for raiders.
Guess what's going to happen if this spec gets toned down ?
And may i ask who asked for another cooldown-based, ST talent, when the spec was in desperate need of on demand, multi target capabilities ?
