At first, I really looking forward to play TEL soon

Good job there, MI.
System / GenerelI would prefer single reports like at single league. I also would prefer that people host one Elite each. But it should be possible to report just one Elite. For "Best of Series" there are tourneys, I think thats enough.
Pointing system analog Single League, I'd say.
Playoffs To get into Playoffs you should have at least 50 Single-Elite Games reported and be at Top 8 at ranking.
LobbyI really would prefer that TEL games should be played at "non-knocking channel", like #pt. If both players didnt agree / forget to play at #pt, they just have to find a solution by themself if any knocks "kills" the game. If they cant, game should just be voided and rehosted.
SchemeUse Elite Scheme from TUS only. But thats not a problem I guess
Maximum Amount of playing same oppenentI vote there should be a number of games which you can play vs same oppenent. I'd start with 10 games per season / max. 4 in one week.
Complains As managed like at other leagues, no "extra judgement" needed.
MapsPlaying at saved maps or maps from a open map pack should be forbidden at all. Only "island maps" allowed, no caves.
Thats all I have in my mind, so far.
