I doubt it. Its a good class for people from state or a country that does not allow highcaps to be able to go to other places and shoot the way they practice. I could be wrong of course, but I think its cool for idpa shooters to swing over and shoot their cdp guns with 10 rounds mags and for all the single stack shooters. We have a few guys around that shoot idpa mostly and can shoot with the ipsc guys with just a few more mags.
As for BulM5 you can still use 10 rounds even if it goes away! Come back and shoot limited against me. Wait till you get bumped to A L10 also then you will start shooting Limited again.
