Alright, I'm 0-4 on this bcnm, and I'd like to hear any strats BG has on this. Our PT configuration was:
whm/blm (me)
nin/war
pld/war
smn/whm
rng/nin
blm/whm
They don't seem to hit very hard but their job changes are incredibly annoying. It seems Yellow Liquid's been buffed in a recent patch, but I'm not sure how much that will help since the nerf in october.
First fight - we gather them all together, SMN Astral Flows them, but now he doesn't have enough MP to keep one of the mammets busy. We got the first mammet down to 25% hp before death.
Second fight - death.
Third fight - Our best so far. NIN practically soloed one of the mammets, getting him down to 25% HP before dying from lack of hi-potions. SMN effectively keeps one of the mammets busy before he's out of MP. We manage to kill one of the mammets but RNG dies from AoE before I can cure her. By this time, I'm nearly out of MP and the Mammets finish us off. Death.
Fourth fight - without meds, we're sunk. Death.
At this point I'd like to question what crack SE was smoking when they made this BC.
