I agree rush groups are part of the problem. They are not all of it however. 90% of Plasma Pyramid groups won't be rush groups as that type of group really needs some good players to succeed, and the good players pretty much all have everything they need from the Pyramid. Killing rushing will unfortunately disenchant yet more senior players who already have next to nothing to do right now. I hope they make it harder to rush in AO3 and subsequent high level maps. The key however is to make the maps challenging and fun to clear. Rushing is around as it's the only challenging mode of play left for the good xp maxed players.
