Well here is the thing about The Elder Scrolls Series and Final Fantasy Online games....TES is a console game not an MMO. And XI and XIV are MMO....so....there is a world of difference I think when it comes to designing these types of games. In TES is only you, and maybe some summons going through a sandbox type environment.
Typically people who play MMO's want to be able to team up with a friend (duo with a buddy like me and my husband) or make a large scale party to take down some baddy...
I wouldn't want another gaming company who doesn't have EXP builing an MMO coming in and telling another what to do....Now....if you want to say Blizzard should say "Hey SE...want a hand?" then yeah...I would say "Blizzard you should probably like...help out your competetor" or somethingThey at least have successful exp making and launching an MMO (BTW I've never played WOW so no I'm not trying to say I prefer one or the other, just making a point...comparing apples to oranges..."
