Vex. These -blam!- cover up their precision spots and i hate that. Their teleport mechanic always lines up with my fire rate at least once, in D1 minotaur had no weakness, and cyclops' just has so much splash dmg i feel like im hiding from wardcliff coil behind a pencil. Great faction in general but those are the things i detest about fighting the vex, in that they challenge me more than other races.
