Scruff_The issue isn't that people don't know about it, the problem is cause it's on a weekend and after scrimming 4+ nights a week before and also people have lives means people don't want to play on a weekend also seven winning everytime means it's not worth it to play most of the time.
If people just can't play saturdays, that's one thing, but being burned out by scrimming seems like it should easily be avoidable. These cups are announced weeks in advance. Just don't schedule scrims for a few days leading up to the cup? And not playing "cuz 7 wins" also doesn't make sense. If that's the case, why is anyone playing ETF2L at all? Just play, do your best, and keep the damn cup alive for future teams that will actually make the cup a good contest. And, again, the prem teams have their own bracket now, so weak teams shouldn't be up in arms about 7 anymore either.
