Revenge mode in 1v1 and 3v3? Also: keep team modality.

Very simple: it would be great if it was possible to ask to redo the match against the same people another time. It could work with a voting system: if the majority or the modality of players wants to continue, then the match is done again with the same people as before. It might work up to 2-3 times (more it would be terrible I fear).
A system of accumulation of points from the previous matches could add some sauce to the thing: points are accumulated match after match, and the team that wins the majority of them also keeps all the points.

Also, when there is chemistry between a 3x3 team, it would be good to have the possibility to keep playing with them for a while!
