Warcraft has so much more potential as an RTS than what they've done for it. As an ardent follower of Warcraft lore, I know for a fact that they can very well make a solid game based off the War of the Ancients, as well as post WC3:Frozen Throne (Which would roughly be the WoW period). At least 2 solid games could be created.
Also, rather than games, I've been yearning for Blizzard to make film adaptations for their icon games. Apparently Warcraft will be getting a movie sometime in 2015, after almost 8 years since the idea to make a movie started lol.
