I think Yoshida did a good job in fixing the basic infrastructure of Final Fantasy XIV. He took elements from western MMORPGs (mostly RIFT and World of Warcraft) and applied them to a visually beautiful Japanese Final Fantasy game.
However, I think now that there's a good base to work off of, Square Enix should consider bringing back Tanaka as lead producer & director, retiring Yoshida from his role as director and perhaps giving him a co-producer role to aid Tanaka.
I am in no way bashing Naoki Yoshida. I think the World of Warcraft elements were a good way to get this game on its feet. However, I don't see Yoshida as an "ideas" man. So far, he has only really looked to other games. His ideas for future content are mostly "adding something from (insert popular game) into Final Fantasy XIV".
Basically, if we stay on the road we're going on, we are going to be waiting for a new patch every few months, where our old gear will become irrelevant -- do the new content, get newer gear, wait for next patch -- that gear becomes irrelevant, grind the new content, wait for next content -- etc.
I definitely think bringing Tanaka back would steer us in the right direction and I think that Yoshida has fulfilled his purpose. He did an amazing job, but I think it's time to go.
