The thing is that you need to be active on 3 platforms at the same time, jump back and forth simultaneously and kill the bosses in a controlled way. After all the nerfs and with current gear the dps isn't much an issue, it's all about execution (you could go in with e.g. 5 healers and still pull it off). I can think of ways to cheese it as a boxer, but it will be one of the most timing intensive fights out there.
