Personaly I believe the "targeting" system is old and boring. And then you add battle-mechanics content...well, that is why I stop playing this game for 6 months. Honestly, unless you are a Final Fantasy fan, there far more entertaining MMORPGs, end for free...Action based battle systems are, in my opinion, way more fun tha this "target" system.

So long story short: action game á la TERA + FFXIV end game mechanics + flexible PT builds from 4 up to 24 members + capping number of attempts + ... oh yea! also make fights mechanics random and not scripted and I can pay 12 USD a month to play that!
But I know, that is just a dream. Target based FFXIV is here to stay, so at least I hope they can make content at least based more on timing and managing CD (player skills) instead of "play T6 until you learn it by heart and then find 7 ppl who also know it by heart and T6, the end." type of game.

Anyways, just my 2 cents. Sorry for my grammar/spelling, english is not my first language
