I don't think that the sport itself, as in people of it, has any illusions about L10. In regards to a specific potential match-up you alluded to, I don't think there is much illusion about as well. Shane shooting 343 alphas vs Ben's 403 for a gain of whole 3 seconds would not leave much to imagination if they both shot minor pf. I don't really think L10 dilutes the scene than much.
Personally I don't care if the organization goes after barely-there divisions. I am more concerned about them not doing anything about previously popular divisions that are starting to decline. I may have been still shooting Production if it were with 140 mm mags, but that's a different discussion.
