Just like the title sounds. I'm new to collecting, and I am finding the Deluxe class TR figures to have some really fun and inventive things going on: Mind Wipe's wings becoming his bot legs, or Hard Head's transformation in general. On a smaller size class, I'm still impressed with Wheelie's transformation, especially for a legends scale toy. Even if he was a Deluxe sized toy, I think I might be more impressed with him than most of the other figures I've purchased so far (which, to be honest, is only a few ) Conversely, I thought Highbrow was a little on the simple side - though I did like the way his legs collapsed when going into his Helicopter mode. I'm coming to realize that a lot of what I'm experiencing for the first time has been going on for a while in terms of transformation engineering, but it's still all new - and fun -for me. Conversely, having watched some transformation videos for more complex toys - usually 3rd party - there have been times when I lost the excitement I had for a figure because I realized I would dread switching back and forth between modes (not trying to pick on 3P here, just the examples I had in mind) With all that in mind, what makes a TF toy fun or a chore for you to transform? Thanks!
