Used in oly by mages that run out of mana quick eg: OL. Used in pvp by all mages including SPH/ST/Sorc, not just Sps depending on if there is tattoos such as tatto of avadon, it increases ur c spd so that u can have same c spd as u wud with DC, but +17% more m att and +1 int with MA robe. You have to think about these things, MA robe is very useful and has Stun resistance, More p def, and SO much more m att.
