It is abuseable but medica II is by no means cheap MP to spam for it's proc. Considering the regen time on average you should only see the proc once ever 30seconds. How many cure I's can you throw off in 30seconds for that freecure? making cure III targetable instead of making it being a small aoe around the primary target would be a good touch actually. Still it promotes group up raising the risk for an npc ability to hit more people, most fights people spread and getting them to group for a cure... I don't see that happening unless a npc mechanic like ifrit forces grouping. That's really the only reason I don't like small aoe abilities. Medica range is big enough to be useable but I don't want to replace it with cure III and following the trend of cure I & II being single target i don't see why cure III doesn't heal more than cure II and leave aoe to the medica combos.
