Hey duders, maybe some of you knew the ole dota-leagueth of the battle.net times ; It has now been ported to Dota 2 !
For those who do not know, this is basically a unofficial ladder system : wins give points, losses take them back. As of now there isn't enough people online at a given time for the matchmaking to make sense (It's still on 'beta', scheduled to be released on the 4th), but i expect the system to expand nicely with a growing number of players.
I have only done 3 games so far, but all have been quite enjoyable, without one side stomping the other or quitters ruining the match.
Word of notice though, there is a 300+ wins entry requirement (You have to allow sharing of your stats, this is verified through dotabuff)
If i'm not mistaken, the Team Cup does not give you anything. Every compendium match (The matchmaking with prepicked heroes) you win gives points to your favorite team and player, and at the end of each week, the ones with the most points get Dota2 items with a special rarity (displayed on the right page). The tournament prediction segment of the compendium has a 'winner' prediction that you can fill out, although I am unaware of what the rewards will be.
As for the choice of a team, you can find the results of recent matches on dota2lounge, and check the prior performances of the teams in tournaments via the Dota 2 wiki.
(Me) - 560 wins - Cap & Carry / Support - EU West ded game - 839 wins - Carry / Ganker - EU West Louk - 534 wins - Carry / Offlane - US West Elgo - 376 wins - Support - EU West ab - 954 wins - Carry - EU West Koubs - 1703 wins - Support / Ganker - EU West
US East is sorta fine for us, US West is near unplayable ('cept for Louk). I'm the only proper duder in the team, sadly.
@do_the_manta_ray: Following your idea of not giving specific times for the matches, I suggest giving the teams a deadline to come up with a match result. Let's say one week for a tournament stage (ie one match per team), since it has elimination you'll be done in a little more than a month.
