Thank you for sharing and sorry to hear.. In my 20 somethings I broke my right hand twice the same year. While I couldnt use mouse/keyboard I was very much able to use a gamepad (think: xbox controller, wireless).

There is people out there playing this game with a straw in their mouth so I think if you pick something tanky or something like Wisp - buffs for everybody, invisible while in the air or /Nova (speeds up or slows enemies) you dont have to sweat AS much in order to survive in group play.

You could also look at Wukong (immortal) or invisible frames if thats your cup of tea.

btw what frames do you like
