Race to the Challenger tier!
We're going to be tinkering with the League System tuning values shortly in order to give people a chance to make it to the Challenger tier in the next couple days. Once the changes are in you'll start gaining vastly more LP from a win than you'll lose from a loss, and you'll note that you're sometimes able to skip a division when you get promoted (as long as your hidden MMR is high enough).
We've also set the max number of players/teams in Challenger tier to five and removed the grace period for being immune to demotion, so once you make it in, you'll have to battle to keep your spot. :)
These values, as you might guess, will not be reflective of what you'll experience on the live server.
Good luck and have fun!
