Standard more still has the potential for game breaking new cards, just less of that potential. It also gives the devs the ability to ban a problematic card without removing it from he game. My main concern is that with all the new queues, matches will be even more tilted than they are now. Remember that unranked likely takes the blow from pool depletion because it's the only mode where matchmaking disparity can be directly observed. Of course I don't care who I face, I just don't want some poor F2Per on a win streak to get thrown in the pit against me.
