I must've inadvertently insulted Rathalos' mother or something, because he focuses on me for about four or five attacks in a row when he's after me. Stop chasing me with that poison swipe, you ass.

That being said, while Rathalos is an interesting fight and something different from the usual EX fare, I think it's a bit overly punishing to end the fight on three deaths when Healers/DPS basically die in one hit (or get stunned and then probably die to a follow-up hit) if they get touched even once.
