So this i think is something everyone has had the unfortunate experience of. You Q for Titan HM and get placed on a team of BARELY item level 57 and that simply is NOT sufficient for taking down titan. VERY seldom do you get a team that can pull the DPS required to make it past heart phase, afterwards it really is just a skill check. To avoid the DPS check I think the item requirement needs to be bumped up to 70, that way the only thing you need to worry about is people actually working through the game mechanics.
