Guild Wars 2

I think there should be 3v3 or 2v2 tournaments, because some people like the strategic combat that they offer.

The maps could be fairly simple and small. Like one could be a big circular arena surrounded by lava and another one could be like a rectangular hallway with a circular center with pillars.

There could be like two gamemodes

Elimination

time limit about 10min
no spawning

Win by eliminating the enemy team

On timeout:

The team with the most amount of players wins

If equal

Team with the most amount of players not in the downed state wins

Otherwise draw – minor (or no) rewards for both teams

King of the hill

normal capture mode but just with 1 node

first team to score 150 points win

time limit about 10min

Great idea, i got something alike in my looooooong post about PvP. Thoug the lava should go up when the time limit goes off, so the players will eventually die in the Elimination
And the one surviving will win, if its a draw, then what you wrote.
