changeling refinement project

[Darkmajia]

i'm making a list of goals for myself to refine changelings - feel free to suggest more in the comments, or contribute to any of these yourself. changelings have been untouched, besides the transformation sting removal, ever since they were introduced and don't seem to have received too much adjustment on goob, at least in terms of easily searchable pull requests
