With upcoming update that allows easier creation of 6 stacks, wouldn’t it be a nice idea to add a map ban feature? Each team could ban 1 map, so we could avoid some of the maps which are just annoying.
It would ban max of 2 maps each game (if both teams would choose different map)
It would only be set for example for 6, 5 and 4 stacks - team leader would choose the map - to avoid bans on multiple maps in one game.
It can be also a great tool for Blizzard to see which maps need some work done - ban numbers on them would be much higher than average.
