Brigitte (on launch) having the longest stun on the shortest cool down and being able to stun anyone/everyone at will was a problem. Once that got toned down and she can’t play like a bull in a china shop anymore the CC feels a bit better in game. As a lot of the boop like CC or ULT based CC at least feels as if there is decent play/counter play at work.
You can still fight back when you get booped or get bumped up in the air by a hero. The CC ULTs take time to gen and they have decent counter play and/or require fallow up. McCree has to take some big risks to get a stun off on a front line hero (unlike brig).
Sure Ana’s sleep is a bit harsh but again, shield block it, it’s aim based and pretty easy to bait out. If she misses on a dive hero odds are she dies. So high risk, high reward.
The CC is slowly getting better… most of the time it’s your main tank that’s going to take the brunt of the CC from the other team anyways. Suck for them but taking one for the team is what tanks do.
