Reading this thread is sort of sad. As small as this community is, it is sad to see you folks fight and hurl insults. All that aside, I would like to contribute to this thread.
When this game was first released I couldn't stop playing it. My friends from other games joined me and we played for a while together. Back then the only thing to do in the end-game was fight a big transparent blob thingie and herd wolf NPCs in missions to power-level our low level characters. I regret that the most. The whole fun of this game IS the leveling up and the experiences you get while doing it. Friends starting dropping off here and there for various reasons, although the scariest one was some of the changes didn't sit well with them (some nerfs I guess). Maybe some of them thought it would be another DAOC or EQ. Others left to play that monster we know as World of War-crack (errr craft). I continued to play until I wasn't having fun anymore.
I went to other games, mainly WoW, because that is where my friends were. I hated that cartoonish POS since the moment I played it, but I could NOT convince my friends to play anything else. These were people I played with for years and years, since the days of Ultima Online. I've given up on even trying to convince them. Warhammer came out, I tried it. They didn't. Age of Conan - same story. Champions Online - same.
Where am I now? I didn't have many choices to be honest. No other game has been as fun as CoH was for me when I played it. No one I knew was playing it anymore so I was hesitant to play it again. To be honest, I hate to play alone. So I'm back. I brought my son with me too. We will play until we get bored again or something else grabs our attention.
The thing is, many MMO players are just not going to make the switch from The Evil Empire (aka WoW). They are so sucked into the lemming pit it is, and what they can "get" next, that they won't even think of abandoning their hard work (I thought games were supposed to be fun) for something else, especially an old game like CoH.
Your best chance to get new players is from people who are "new" players. This Facebook idea is a good one. I know some of you don't agree and might even be prissy about the types of players it may attract, but I think this game has a LOT to offer fans of super-hero games or even movie fans looking for a new experience after watching a good super-hero movie. It seems that the people running this game have somewhat of an idea of where to get these customers. They certainly won't get them advertising on Fileplanet or other gaming web sites. People there are either disenchanted with all MMOs or are hooked on World of Suckfest, or they are like us, willing to play their favorite MMO even with less people playing it.
It is sad that some of you don't care to see the population grow and like it how it is. In order for new content to be released or anything new, they have to make some profit on the game. The status-quo isn't going to do it. They will only do this until they have something else for these developers to work on. Suits don't care about customers - they care about the bottom line, and if you think they do you are greatly mistaken - especially in a country where they are willing to send all our jobs overseas just to make the mighty dollar line their greedy little pockets.
So anyhow, you have two "sort of" new folks coming back to play this game. I'll do my best to drag others back! I don't expect much though. Haven't you seen the advertisements of the new WoW expansion?

They have an army of developers to throw at another grind-fest for their customers and by the sound of my old friends who play that nightmare, their eyes are already lit up and their money is already waiting to be spent.
