I highly doubt there's ever gonna be a warmer scene again. Most of the good ropers who still play don't care about warming, myself included. (Although I'm taking a break from the game.)
I don't recall seeing a warmer hosted for at least a year, probably. There's people who like to play various types of ropers, as well as TTRR and BigRR but warmers? Not from what I've seen.
I've always personally been the type of person who doesn't see the point in warmers anyway. It's just endless f@#!ing around and no end goal aside from doing some cool trick combo like we're playing Tony Hawk on PS2. I feel like I've seen enough warming to last a lifetime already... but that's just me.
