I find the game to be relaxing, the combat with a controller is top notch and is definitely the best part of this game for me. I do not like it very much on mouse and keyboard, though I have to say I have only played it for about an hour or two with M/KB. The auction system is jank, I don't really sell anything. But, in all until later in the game, gear doesnt mean anything. You basically just want your gear to give you bonus EXP %. The graphics are amazing in my opinion and I feel that some of the artists really felt excited to do the job. The game can be played quite easily as a single player or 1-4 player type setting with a few friends. I find it best with duoing. You can go anywhere and quest to your hearts content, but fastest leveling will be grinding groups of enemies. There are some new additions of raids, dungeons and heroic style dungeons.
Ya know, one thing I do like as well is having to pick your "best" skills. This kinda reminds me of EQ sometimes where you have slots, you cannot hotkey the entire skilltree. You basically pick around 6 skills and an ultimate and a few potion slots and you cannot swap skills in combat (kinda swap skillsets by weapon swapping).
