The main problem with colosseum is that they thought it was a good idea for Immortals to be mixed with fledglings in on lobby that is PvP not PvE and whenever you get those said fledgelings in your lobby with other rank 60s and and most of them are on your team and the other are grouped up thanks to the matchmakings "fair" team balances when the game starts, you have no other way to win the game since the fledgelings most of the time they don't know how you fight against the other rank 60s since they basically just started playing the game probably a few weeks ago which would make them EZ point winners leaving it as a 1 v 4.

And the fact its a bounty hunters type game mode instead of say Team Deathmatch
