Blizzard’s Cold Snap talent stops troops attacking

I remember this talent was nerfed by cancelling the stunning effect on troops. Now it came back again.
By the way, PvP is extremely unfair. You just need to use deep breath to attack your opponent’s base, all else you need to do is just playing some minis when enemy are close enough to your base, because this super powerful rocket tower is going to kill everything.
What about those players who don’t have deep breath?
