From what I'm seeing, ESEA has no interest in supporting TF2 unless the players just flock there of their own accord.
The moment a quarter of the playerbase is discontented enough to flock to CEVO , they're just going to drop it without even trying to do any outreach? This has been eminently foreseeable for quite a while now. The fact that they've done nothing to attract/retain players says it all as far as I'm concerned.
Seriously, why should new/low players go over to a league that doesn't give two shits about us? I get a lot of the higher level players arguments, but they're largely selfish reasons, where are the arguments that might have some chance of convincing people instead of condescending to them?
If all that's holding 6s together is the vague commitment of ESEA to keeping a league running, then the game's already over, it's just a matter of this season or next.
