They gave up on keeping the 3 specs competitive.
The same way MM is shitty for pve, SV is for pvp, u just have 2 specs to choose. If they even cared a little about SV pvp they would give the Silencing Shot baseline to SV too, and even other things.
About SV pvp there are tweet posts that they really gave up, probably the same is going for MM pve.
