I personally liked the Evolution system in Monster and me. You evolved certain pets in specific locations to get different outcomes.
Perhaps they could impliment this feature in CT, except instead of being in a certain location, whenever your pet reaches a certain quality (30* 40* 50* 60* 62* 65* etc....) Your pet evolves and looks a little different than it did previously. This would make people more interested in composing and give them goals and things to look forward too :D
Just a thought.
