I'll be honest, if this is an MMO the "new content" will be a couple of story missions, and then more raiding. That's all it ever is. Progression is either levelling the base character, or gear progression through raids. If you don't like the pvp, there will be literally nothing for you.
COD is about as appealing as an AIDS infected whore, and GTA V was great, but 'been there, done that'. I'll try to get into the raid, if I like it I'll buy the DLC, if not I'm in the same boat as you Phil.
