As a new player to the COH community it really sucks that parts of the game that appear to be functional are not. The base raiding idea maybe better suited as part of Rogue or limited for Rogues and Villains vs. Heroes and visa versa. The CoP or mission computer arc should have many different almost unbeatable missions within almost like AE. Honestly, after a certain time to save time and ideas you could take the best and most popular AE mishs and reconstruct them into CoP trials for new IoP's.
Really, it's retarded to have gaping holes in any game.
