after looking at the toggle aoe answer it occured to me.

they are basically going to kill or marginalize all unique elements of ffxiv battle. thinking about it and remembering what matsui said,

Thank you for taking the time to pore over these words. Having read the blueprint, there is bound to be more than a few players who feel that we’ve only recited a handful of things common to all MMORPGs. There may be others still who are saddened - perhaps even piqued - that elements they felt made FINAL FANTASY XIV unique will be going to the cutting block.
he starts off talking about the fact that it sounds like they are jacking all other MMOs. then he states that features that are unique will be killed off, i had thought this was just about AA, and maybe a few things getting cut, but nope. They are going to try to remake the battle in a classic MMO sense. Hence the old school job upgrade, traditional roles only. 1 class is 1 job. AoE Mage mechanics is going.

So basically they want to do regular MMO battle mechanics, and i guess all you can hope, is that they do it better than other developers. hmmmmmm sounds like ... bad. ehhh
