Getting randomly knocked out of stealth can put you way behind before the game even begins. Keep in mind that every class has gotten access to more and better(bigger radius/passive) aoe abilities to knock people out. In the current game just removing subterfuge without giving us another way to get successful openers would make the class very hard to balance (ie, inconsistent.)
Of course there will always be people complaining about abilities they find annoying, and trust me I can list things from every class that is at least on par with subterfuge in the "annoying" aspect.
Subterfuge and C&D isn't OP. Accept it, adjust your play to be more defensive during openers vs rogue teams, and I can't emphasize this enough, PAY ATTENTION TO THE DAMN GAME AND STOP LETTING ROGUES GET FREE RESTEALTHS OFF. You have no idea how incredibly simple it is to get restealths atm without people even trying to stop you if you know what you're doing (and pretty much 90%+ of all restealths I ever get could be prevented or taken huge advantage of by the opposing team if they knew what they were doing.)
like you stay stealthed for 3 seconds after taking dmg, but if you open you instantly get de-stealthed?
i dont know, i just feel the talent is kind of stupid and overpowered, we got a "noob friendly" vanish in cata aswell.
