I think what annoys me, and I play during the daytime EST, is how hard it is to find people who want to do something other than use the game as a chat program. I play mostly LoTRO and AoC now, but I still think CoH by far did both the solo-group balance best. Additionally CoH made it easy to meet up with your teammates and do stuff. Stuff scaled rather well from 2 to 8 people, you get mission XP whether you have the mission or not, the addition of radio missions makes it easy to put together a group of spastic savants, who can't stand the thought of travel times over 35 seconds. Also I think one of the reasons why the more loot centric games see more solo'ing is that with the way drops are done it kind of discourages people from wanting to do stuff with other people
