I agree that Titan is seen as somewhat of a check when you're gunning for a relic. It can be slightly unfair to go from never having to worry about DPS checks (because there are practically none until this point) to being slapped in the face with one and immediately follow it up with a rotation that is designed to catch out DPS that are still focusing efforts on their rotations. But it's the players that have nurtured bad habits with FATE grinding etc and turning around and setting disproportionate ilvl requirements that has bred inability to cope with late game content.
