Too soon, low and "new" level accounts reach 40k - 60k power and stand on top rankings. It's because each account in merged server got a lot 'build rush' compensation and low level accounts got most benefits from that because their research list were empty.
It's fine, you may say, anyone can get it. However top 1 player research rumble with his most research is .. 60 is completely weird. Especially in a server with most players got 140+ power and some are 200+ research power, such low level accounts could do nothing, they just appear to get rewards and disappear forever, they don't play, they just spoil the game.
