There's a lot of differentiation between joining a xlpc and hpc. And making newcomers train their accounts gives them less incentive to stay in the scene, especially since it's so competitive. Yes, Zenith had some success, but if you're suggesting that 50s-60s being recruited into the hpc scene is more sustainable than recruiting them to a less competitive scene that gives them more incentive to stay, you're misconstrued.
Rogue xlpc's bringing 70s or hpc's that attempt to undermine the scene will have little to no success. We intend to keep our brackets small and if fighting sub 10~ wildy means keeping higher brackets out, then that's what we'll do to keep them out.
