Since the last update matchmaking has changed dramatically. There must be a infamy factor in mm calculations. As experienced player it is boring to slaying new bees with a 1/100th of infamy and as a new one it must be very frustrating to get sloughtered by x1000 infamy players. Actually a lot of players using low hp fleets to get infamy over some 1000th, but I think over 5000 must be very special for experienced active player's to keep some long time motivation.
Thanks for the lovely game, but please do something to make it really successful.
