Speaking as a JQ player, I don’t have a problem with this. Over time, alliances will be made, broken, remade. It’s the nature of this sort of game play (along with all the threads on “night capping”). This isn’t meant to be “fair” gameplay. Forced ballance/fairness will ruin WvWvW. If that is the sort of gameplay you are looking for, I suggest you stick to sPvP.
Not seeing a problem in need of a “solution” here. We dealt with this in DAoC all the time. It’s part of the game.
