Fortunately most of the tracks around here don't follow ROAR rules, so I'm hopeful that trend will continue and we will still have boosted classes. They are the most popular classes locally. Also I own two Tekin ESCs and I'd prefer to not have to buy new spec speedos to replace them.
If they want a zero timing 21.5 class for stock, fine, but banning dynamic timing ESCs that have zero timing modes is ridiculous and I think they're likely to lose more racers if they decide to go through with this.
