3.11 is pretty strong too:
Season 7: Billy Hoyle's Boys, champs, now ABBL
Season 8: Rampaging Marmots (totally awesome) (may have relegated back in to III.11 after a season...)
Season 9: Upwey Flames (got relegated from II, lost interest and botted)
Season 10: City Celtics (got relegated from II, got back up to II, got relegated again, botted)
Season 11: Tassie Guners - won III three times, kept getting relegated from II, lost interest and botted (this season, Marmots went 22-0 and still couldn't win a finals game)
Season 12: Kynlala Knights - need I say more, iwen's team, amazingly good trainer/coach/team etc. (season noteworthy for the Marmots again going 22-0 and getting knocked out first round of playoffs)
Season 13: Chelsea Seagulls - again, don't need to say anything more here - awesome team.
Season 14: Rampaging Marmots - hell yes.
Season 15: XBB, been around for ages, made it to the final 32 of the Cup once, now has seemingly lost interest and fallen to IV
Season 16: Ratman - stayed in II for about 10 seasons or something, trained that awesome NT PG whose name I forget, now botted.
Season 17: West Coast Steel - current II.1 (spare a thought for Villians who, at this point, have won the last 3 Great 8 conferences and have gone down in the final game of the playoffs each time)
Season 18: GoldCoastSH - current II team
Season 19: Has urmummas, 22-0 and looking good to take it all, and still has Villains (former ABBLer, been around since season 2).
So, not as strong as 3.6, but has still had Kynlala, Seagulls and Marmots come through, as well as West Coast Steel who should be strong in the future if interest is maintained. A lot of teams won and then went bot, though :P
