The only trouble I seem to have in dungeons comes with the last boss apparently. I tried Toto-Rak last night as GLA and everything went smoothly until the last boss. The adds appear, I grab them, and then have the squad engage the tail, but the healer completely stops healing me. What's the deal? When the tail is dead, do I have to re-engage them on the scorpion or what to keep the heals going? It's just like Cecily clocks out and says, "Nah, he can die."
