The latency is whats killing most people, the fights give no room to breath and are hard for casuals or those who aren't elitist. Ifrit and Garuda could use a 5% nerf at most, while titan could use a 10% nerf. Ontop of that, make a gear check when you que up. You shouldn't even be able to que for titan unless you are full darklight.

IMO...
AK: darklight accs
ifrit: Darklight accessories + at least 3 pieces of AK armor
garuda: darklight accessories + at least 3 peices of Darklight
titan:full darklight or better, either previous primals weapon.

binding coil: darklight + at least garuda's weapon.

Dungeons need a gear check, at least for endgame.
