Here's some calculations of how many teams we had in ESEA, CEVO, and UGC, and how many combined. Keep in mind that this doesn't take into consideration overlap between leagues so there's at least some inflation here. This means the total number of teams is actually lower. Also, it does not account for dead teams, but that was an issue even when we were in better shape. I included UGC as it gives a picture of what our pool of potential new ESEA players we have.
ESEA S15 had 85 teams. CEVO S3 (just prior to the paid league) had 34 teams. UGC S14 had 264 (!) teams, so that's 383 teams total. ESEA + CEVO was 119 teams.
ESEA S16 had 62 teams, which is a pretty steep dropoff from S15. However, CEVO's paid S4 had 126 teams and UGC S15 had 306 (!!) teams, giving us a total of 494 teams. ESEA + CEVO was 188 teams.
ESEA S17 had 63 teams, CEVO S5 had 103 teams, and UGC S16 (still in playoffs) has 243 teams. This gives us a total of 409 teams. ESEA + CEVO was 166 teams.
In addition, GXL had 25 teams. Not sure how this compares to other LANs, but it's definitely the biggest NA LAN we've ever had since at least 2012.
CEVO S6 was cancelled due to a low registration rate (as Lange pointed out). ESEA S18 currently has 47 teams, and none of them ready (it's still very early in registration though); this also includes mix^ and other dead teams since there's the chance their roster is used to form a new team. UGC S16 playoffs are still going on so we won't hear about their S17 for another month or two.
If ESEA does not even reach 63 teams, then TF2 is probably on the path to a quick death. If we have even just 85 teams in ESEA, then I'd say we can at least hold on for a little longer. If we can keep the UGC team numbers up and actually get these people over to ESEA, we could end up with a new age. However, with mix^ dying and the recent update, I'm not sure if anyone outside of our community will be able to take comp TF2 seriously.
I'll stick around the community for as long as it's still around, but I don't know if I'd become active again. If I can get my schoolwork organized so I have time, then I might be able to stream matches assuming we can get the 45/5 plan from AT&T since my parents are cutting TV out to save money (our only other option for Internet is Comcast which my dad will never get again).
KanecoAmerican scene is in a dire situation because you got 3 leagues for such a small playerbase, 2 of them paid leagues. It only divides the community. How the hell do you sustain that kind of stuff with such a player base? Even esea got rid of main because there was not a big enough player pool.
^ CEVO TF2 is dead. We're back to 1 paid and 1 free league. We may still see a drop in players. To be honest, if we just want to play TF2 competitively for fun, then we might as well just drop ESEA and 100% commit to UGC or ETF2L. There's no need for a LAN that only four teams can participate in unless we want exposure.
