This game has quite possibly the single most fractured community of any game I've ever played, Nightmare is to blame. The fact that the community -- or lack thereof -- is fairly small makes matters all the worse.
I've bought the new hero pack and Quest for Shards 1, the DLC that interests me. I've reach 74 with four toons, bought/found low/mid range mythic gear for each. Now I find there's nothing left for me in Dungeon Defenders.
Logically I should progress to Nightmare, but without pre-ordering the DLC, it's nigh impossible to get into one of the incredibly few NM games that are up at
