You know, there's a difference between keeping up with your competitors and being a WoW clone. I think that terms gets thrown around too often and too easily. MMOs, as part of the same game genre, are going to be similar to a degree. This is not a bad thing. These similarities are often systems that ended up working well or for the best.

I'm not worried unless ARR ends up being a literal WoW clone with better graphics. I don't see that happening.
