No one is picking on Flames, people just want to get first place.
Frontlines is a tactical game, people are going to attack and hold the weakest links in the enemies defense. If a GC is failing to hold points, people are going to send forces to take those points from them. Its nothing against the GC, it just a good way to earn score in a domination style gameplay.

Really if a GC fails to push us off the middle point between the two GC OP and doesn't push back to push us off or keep us busy... do not be surprise if the we "pick on" the GC fails to keep us in check.
