If you don't know what it is, I will be ashamed.

It's made by Swedes and it's in closed Beta right now. It's just playable during the weekends.
It's like arena in WoW but fun. You don't need gear, you've already got all the spells. There is no luck/bad luck (dodge, miss, parry by chance) it's all up to your skills. Controls with WASD, mouse and 5 more buttons.
There are (I think) 16 champions, split into tanks, melee DPS, range DPS and healer. There can be more than 1 of each champion in each team.
The creators aim more for making it even than making more and more champions.
Currently there is only fight to the death. You win 4 times and you've won the round. They said they were going to make CTF and alike, or maybe I've misheard.
Every spell is colored (teams are red vs blue (actually Warm vs Cold)) so you know completely if you can run through it or not.
Sign up on their website, it's ABSOLUTELY WORTH IT!
