Would like to see the option for default 'saves' for preferences on pre-round upgrades per character.
Would like to see an improved UI for the partying system pre-lobby, and better ui information (you can't even look at character information like abilities while in a party it seems).
Being hit makes it feel like you are getting mini-stunned every single time. This needs to be improved to feel like you aren't getting CC'ed in the melee cluster fights. Needs to be more responsive and less clunky feeling. In general TTK also feels a tad on the fast side.
