I'm having a really hard time healing the end game dungeons as a WHM. I don't think it's the dungeons themselves but I can't seem to keep up with the enormous pulls (10+ mobs.) When the tank is finished his pull (despite me having SS on him), he'll be at like 100 hp and it's so hard to keep him alive.
I use Presence of mind, divine seal, etc. but I'm just spamming Cure 2 to the point where I go from full to OOM in what feels like 30 seconds. It feels like I'm not actually healing him because his HP is still basically the same it seems. It's like what I heal is instantly getting taken away. I tell my parties that I'm new to the dungeon but that makes no impression. We wipe only do to the trash. Boss are easy peasy.
How do I heal with these huge pulls? Dear Lord! Please help me. ;_; I haven't even tried the hard mode dungeons. I thought the normal level 50 dungeons would be a good starting place but apparently not. Halp! Halp! Halp!
