Sorry, I really hated the all of those systems you mentioned. I found them really pointless and annoying. Just my personal opinion. I would much prefer if they did it the FF:tactics WotL style. I have not liked the leveling up systems in the FF games from 10 and up (excluding FFXI, I liked the subjob).

They did a sphere grid thing with Path of Exile (a diablo ripoff) I really liked the gameplay and how it felt over Diablo III but once I realized they used the sphere grid I dropped the game like a bad habit. Honestly, and I know it doesn't matter in the long run, I would drop ARR if they did the sphere grid.

I like what they have and the concepts they had in 1.0 as long as they carry over the basic system where you borrow skills from other classes then are restricted once you have a job, I think it works great. Then have the merit system to purchase high level skills. Why does it need to be more than that?
