I would very much like way more depth.

It would be nice if we get an in-depth response why they chose not to go this path. The only thing I have read is because of how this game needs to be new to MMO/FFXIV friendly. We got the same argument for 3.0. Notice how 3.0 will be available about 16 + months after launch. One would think most of the new players already joined. If they did not, it should be a great opportunity for them to introduce depth into the game so the new players can adapt right away.

I'd put my money on lack of time. They try to stick with the 3ish months patch promise. There is not much room for overhauling, but that hope though.
