Obviously there are quite a few different opinions on transformation. Some people never even transform their figures, others just once. Personally, the enjoyment I get out of collecting TFs has to do with the interesting and ingenious ways that a figure can be both a robot and a vehicle (or whatever) and appreciating that fully requires at least periodic transformation (for me). That said, there are definitely some figures that are such a chore to transform that they don't engender appreciation for the process itself. So, I'm curious - if you are like me and you do like to occasionally transform your figure, and you appreciate the process for it's own sake, what are your favorites? Which are your least favorites?
