I feel like making 2v2 mode competitive would be a great idea. I think it should not only include ‘2v2 ladder’, which is really popular topic, but not that clear. In my opinion it would be great to make 2v2 Path of Legends in similar system which is in normal battles (or maybe with a bit less steps in some/each leagues). I would also add 2v2 global tournaments (also with the same system like in 1v1 GT), but with rule that you can only play with one partner, to collect wins together and climb top ranking in pairs cometition. I think making 2v2 competitive could let us discover some really good 2v2 players, who are not that great in 1v1. That would open the opportunity to play with our friend not only for fun, but with some motivation for good results.
