The lowest thing I see in the mains is hordes rolling bases on one side of the map, then going to the other side, and continually switching back and forth. It's impossible to put up a defense. They roll your base the first time, you wait for a bit for the next giant red blob and you realize it's on the other side of the map, so you shrug it off, go do something else, and next thing you know half an hour later, the blob is back steam rolling your base. You scramble to land and take off to fight it and it's too late by the time you get there. Cycle continues. Pathetic.
