So,
if you could take something from another game (or book, or even movie I suppose) and put it into WoW somehow, how would you implement it and what would it be?
I'll use mine as an example,
Better Force spells. A force is a push or pull in a direction, and right now we have very limited spells that use force, like Typhoon, Death Grip, and Leap of Faith. A good example of these spells comes from the Dragon Age series, where mages can specialize in Force spells and use a downward force to crush people, an upward force to throw people upwards, or a condensing force to suck people into a point.
Would be fun to use force to, I don't know, bat a healer out of range of their target as a warrior. FORE! *swat*
You can also take bosses from other games, and plop them in WoW. Explain which boss and how a group would need to go about defeating it, perhaps.
Stuff does NOT have to make sense. You can make up totally hypothetical situations that would drive players insane if it were actually in game, like the new warcheif of the Horde being Rebecca Black.
And, now for a TL;DR picture.
Edit: I should note this isn't a "take things out of WoW that tick you off and then rant about casuals for six pages" thread. Additions only, ridiculous or otherwise.
