As a returning player and someone who played the original Dungeon Defenders, the massive amount of difficulties spread across these different game modes makes very little sense with how small the playerbase is, especially when the newest update added a new game mode to play them on. I like the idea of the Diablo-style difficulty levels, each adding new enemies to face with new tactics, but having 3 different game modes feels very pointless. Sure, Incursions can be fun but they are kind of pointless for farming compared to the regular Trials, and the new Mastery mode seems to be just a campaign-style Trials mode. The idea of the different modes is nice, but it severely limits the available game sessions with the already very small community of players. Personally I would just keep the single Mastery mode and get rid of the other two modes. It would simplify the modes and difficulty and allow players to more consistently find matches, probably.
