Now, I will be the first to admit that Wow had a rocky start, and is nowhere near perfect, but I think its time Square subcontract with Blizzard for FF14.
Why? Say what you will about blizzard, but their hardware architecture is flawless. 8 Millions people online without Hitch, minimum downtime ( or minimal downtime ).
Also, a few years ago it was 11 millions. very seldomly did you see a queue or you were unable to login, most of the time, login in was fast and practical.
Now, FF14 has a tenth of those players, and manage to fuck it up.
So, dont let Blizzard touch the game ( I like FF14 better actually ) but pay them monthly to handle your hardware and host your servers, and give them credit for it.
Because it is obvious that SE is not able to handle a good MMO as far as traffic goes.
