So your saying we should bow our mp on something we have little to no control over (don't give me the whole "you gotta bring a blm to enfeeble it" crap). A while back it was proven you could force them to cast AM, but who gives a rip when the avatar spends the rest of the time sucking, and to have most of them cast AM you have to bend over backwards. The only new spell ANY of the elementals we can cast got was Banish IV. They continue, even with lots of summoning magic skill, to sit there and be a waste. Hell, I haven't even had to use Siphon in forever. Also let it be known that I still /whm 9/10 times, even when solo, simply because I haven't had the time to finish my rdm sub. I have sch sub, but /whm offers more grellow procs, so I normally stick to that. If I'm coming smn to a nm, we probably didn't have a healer to begin with.
Also, it has been proven recently that elementals CAN run out of mp, sitting there and doing nothing at all other than lolauto attack. Refresh atma really is a crutch with how easily we can get mp back without it.
