Not sure if mincing words will bring the discussion forward, but I guess Late Game is the more appropriate term here if you disagree on End Game. Which starts around the time of the first satellites dropping, and players nearing their level cap for their first bases.
As for removing players from a server, that seems rather counter productive since its generally in our interest to have servers full, and players generally seem to gravitate to newer servers. So removing anybody who participates in a base takedown would only contribute to server depopulation.
