Yeah MV really needs some fixing. I love that JA. I always activate that when i can and it lands pretty good. Even on Abyssea-NM´s. But the recast time really sux.

Ohhh... and the helix with fully merited MV would do approximately = 711 + ( 4 * ( 711 * 2 ) ) = 6399 DMG
And that for only 79 MP and rediculous low enmity.
