I don't Eugene I've seen some revo shooters who are massive size dudes, bigger than me, and that's before putting their rigs on.
But yes, it does take up space, given the way they assign slots and plan matches like the Worlds, you can only get so many people in, and they have to allow for Revo shooters. I don't really care about the history of the gun, it's a dead division and should be tossed simply on that alone. If it was occupied by a decent number of people that would be fine, but every year it gets smaller. And yes, PDO needs to go to, hopefully the data they get back this year will support tossing it. Stupid idea for a division.
