Cho’gall just got a buff and it would be nice if they seen more action in competitive mode; however, there are issues with picking them. When you go to pick Cho’gall and you are coordinating with another player, it takes a bit of time. if someone locks in something else while you two are locking in, then it blocks the pick. And then everyone but that one person gets removed for inactivity and punished, even though valid picks were showing. One person can make multiple people get punished just because people were going to play cho’gall.
Only way to avoid it really is instantly lock both. Or you get leaver penalty if you are still hovering Cho or Gall when there aren’t two more picks available on your round.
