Guildwars Dodgeball

You can play this 8 v 8 or 4 v 4, whatever suits the number of players you have available. Every player rolls a Mesmer/ele with 5 superior runes (not including vigor) so they have 105 health. The eles choose armor with armor vs FIRE damage (important.) The mesmers need 12 air and high fast casting.

Now basically your team is only allowed behind your side of the flag stand, crossing the flag stand = disqualification!

players only have 3 skills, lightening orb, air attunement and elemental attunement, and have to attempt to toss orbs across the flag stand at each other, once you kill a player they'll have such low health + death penalty means they wont res. And they're effectively "out".

The last team standing wins.

Orbs can be dodged by strafing or moving just as they're cast, players have to learn to kite and dodge projectiles to play this game effectively so it can make for pretty good practice.

(I took this from some forum, so I take not credit for this. Although I think you should be able to take Res Sig.)

I think this is a great idea. Sort of snowball, year round. One thing I see a flaw is the strafing; if someone is better then another would that be really unbalanced? We need to test this.

The more you do it the better you will become. I am willing to test it.

I guess this would be good practice for when in elite areas and group leaders yell 'get back get back' just teasing.
