The currency changes that basically forced people into paying, split focus between being a moba or being a pve dungeon crawler, bugs that were never addressed, balance issues that were never addressed, use of CoH heroes/villains only to be met with backlash from it's former players (I think this was a failed attempt at trying to get some to give the game a try), and constant radio silence from the dev team lead to this games downfall. Shouldn't even come as a surprise. The CoH reddit is celebrating.

However, I will admit the game had a lot of promise. So did Infinite Crisis, but it's gone too. Moba market is over-saturated. If they had just focused on PvE they may have seen better results.
