^ Titan is supposed to be an MMO-FPS, or so I've read. So not really a WoW-replacement.
Re: Mists of Pandaria
I'm optimistic about it. Some things I read from the Blizzcon coverage that resonated with me:
A) A stronger focus on fun. Cataclysm on the whole is not a very fun expansion (in my opinion) and was certainly not all that fun on release with the harder-than-necessary Heroic dungeons being the main problem.
B) Multiple paths to advancement. Valor points from dailies. Raid finder for easy version raids. The time has passed when I wanted to commit to a raid schedule but I'd still like to see the content.
C) New huge continent with no flying till 90 (yay), loved this in Wrath.
D) Melee healer. Healing is my favorite spec and playstyle and an all-new way of healing is very exciting.
One thing I'm not sure about but I hope they fixed is that heroics should not be so dang long as they were in Cata. 2 hours is too long
Anyway, I will definitely be checking it out.
