People say as if it's just for the pros and neglecting the opinions of 99% of the people, but I really cant agree with that. It is neglecting the opinions of the one game mode specialist intermediate players from Voobly, yes, but those people really are not 99% of players. I think lots of noob players playing their first online games actually will enjoy having the chance to play on a variety of maps without having to run head first into a brick wall of arabia meta specialists.
This rather sounds to me like it comes from a spectator/twitch chat guy that only watches tournament games and doesn't actually play on voobly. The reality is: even the experts play most of the time just arabia, if they aren't paid in form of a tournament. As noob you will run vs a layer of bricks anyways if it's arabia or some random map doesnt matter, in random maps its usually far worse than in arabia tho, because water makes builds more complicated. If ppl only want to play that one map, if it's BF arabia or whatever, then they should have the right to do that ranked, else matchmaking will die and with it DE, as aoeDE1 died when there was no rating available.
