I'll add my 2 cents.
so is Yoshida doing a good job sure. is it a great job nope not at all. yes was the game a mess when it was first released yup but i also blame that on SE rushing it out way before it was ready not solely on Tanaka. so do i think he should be brought back nope time to move on to other projects.
now as for Yoshida the thing he did was not really hard, he took a game that had grand innovative ideas that where rushed and poorly executed and he refitted it with ideas that everyone else is doing and just made them run. so its not exactly like he took a very bad FPS and turned it into a bioshock or borderlands. he just took a bad FPS and turned it into a COD clone. now is that a bad thing no, just means it does not stand out and the life of the game will always dip every time a new version of COD comes out.
so do i play ff14 and enjoy it, yes i do, but the thing is im now losing interest and the sad thing is my friends list is becoming a ghost town more and more as the weeks past.
i just feel that as time passes on this game will get go down in a hurry because yes it might be polished but there is no innovation to keep you glued to it and might see a massive hit once ESO hits.
