I know we have a lvling system that is being worked out for the lvl 36+, but lets face some facts that there isnt that many people around to try out and experiment with stuff so we may never find out how to use it. I have a suggestion that may help some people.
I say maybe we should try and take self healing away from coliseum bosses and make them more doable by less people if was to happen. Maybe even go as far as to make the cleric one an undead boss so they actually have to heal it which is what clerics do. Maybe even lower hp just a tad on the bosses as well so you dont spend rediculous amounts of time like hours to get a token. Not sure if any of this would work but its a suggestion.
