It would be nice to see more done with the ghost in the future. I noticed in the beta there is an inventory of ghost "shells" that might relate to different colored ghost or shaped ghost. What i really want to see if this is true is a ghost that looks like "guilty sparks" from the halo series or even a skull of some sorts. That to me would be one of the coolest cosmetic changes to the ghost besides maybe a laser so the thing isn't so useless in battle. lol
