The game's quite fun and has a lot of elements that I do enjoy but I really do hope they they work a bit more on the combat animations and especially give a boost to melee skills and rethink the passive skill tree placement of the Duelist class in particular.
Right now it's pretty well-known that melee builds are screwed after a certain point unless they pick up melee skill gems that have a ranged component to them (ie. ground slam and lightning strike) and even then, those simply can't compete with ranged, totem or caster builds.
Along with that, the Duelist seriously needs a reworking. They're placed in such a bad spot that the Marauder, Ranger or even the Shadow can do what the Duelist does but better and at the cost of less skill points in order to grab the important keystones. As it currently is, the Duelist is the worst class out of them all simply due to his placement on the passive tree.
