I have been thinking about this for a while now, and I still don't know a proper answer. I think tricking doesn't have much to develop at this point, just as it is in real life too (I guess?).
But there are these crazy combos I see people doing sometimes that still makes my eyes shine. In toribash, I would translate them as Glimpsed and Xmov's replays in which they don't bother about making "plausible" tricks but instead they do crazy moves that are really funny to watch.
My opinion, this is the only thing that still surprises me in toribash tricking, at least for "xspar tricking". If we are considering mods there are a lot of ideas that we can still come up with, overcoming the limits we face until now. You are the living proof Mack, you do unimaginable tricks (for toribash standards) in bouncenotramp
