Why does White Mage have Medica and Medica 2 when Medica can just be upgrade to Medica 2 just like Glare/Stone, Dia/Areo.

I know that it is a low level aoe heal and I get that but after some time it should just upgrade. I feel it is a waste of a button when you are level 90.
Like a White Mage could have another potential skill for that spot since we get cure 3 which is a better aoe cure. Not to mention you don't want to overcure so you wouldn't be using Medica 2 that much either.

I'm not saving to make it as complicated as AST but it would be nice to get a new ability that gives more mp back because I feel I go through mp more as a whm than any other healer.

Tldr: Remove Medica when we have cure 3 or just upgrade it to Medica 2 this is silly at this point. (I know you don't have to have it on your hotbar and I don't itvs just a waste of an ability there)
