All the tournaments I’ve seen have been using a draft system for characters. If a character is selected he can not be selected again by the other team. At first I hated this idea, but through playing I now love it. It adds a whole other level of strategy and the best teams will be good with lots of characters.
I think the Competitive Playlist needs at least a draft mode. In a perfect world each team would get a ban or two and legendaries would be banned as well. This way the Competitive Playlist would be similar to tournaments and prepare you for them.
GBX, please consider adding a draft mode to the Competitive Playlist. I love the strict SBMM, but would be cool practicing with and against team compositions that you will actually see in tournaments.
