no game but......COH. Before the GDN et all. They expanded the agro caps for "realism". Is it realistic for a group of thugs to be caught in a nuke and it doesnt hit one of them because he was the excess guy? No.
If you jack up the cap, keep that balanced with the rest of the world. Other wise stay with an agro cap of 16. The game is being changed to satisfy little groups, and is no longer the game we all wanted to come back. adding power sets, missions etc is great. changing the basic world will only satisfy the niche players that are currently in favor.
