Graphics
Better textures - I absolutely love the art style of this game. Some say it's too cartoony, and I think sure, it is cartoony, but it also is a style we haven't seen before. It reminds me of a Disney or Pixar art style. However, more detail in the textures would be something I highly recommend. High def textures is a plus.
Healing - I personally like the healing animation you see in many other games released on the market. My favorite so far is Neverwinter. I know this is such a minimal request, but I play a healer full-time and I like eye candy!
Anti-aliasing - I personally prefer the sharper character models but also a very soft feel, I think this type of AA would fit well with the art direction of this game. For an idea of what I am referring to, please try Neverwinter.
