Jorgurs Dogfight is terrible.
Quite.
But it could be much better. It needs:
Balanced teams. Half the time, one team has literally one hundred more points than the other because it has 20 members while the other team has 7.
No team killing. I have learned from experience that most of the people who play on that server (at least while I am) are immature to the point where they just set off HE grenades in their own team's spawn just for fun.
A goal. I find myself flying towards the enemy team's base thinking "this time, I'll make it!" and when I do, I am immediately disappointed. I just flew all the way across the slopes to spawn kill the other team, and nothing else. Why not something interesting, like capturing their base, or stealing their flag? TDMs where the goal is to reach a certain number of points by killing enemy team members only works if the arena is right for it. Jorgurs dogfight is not right for this goal because, once again, you arrive at the base and are left with nothing to do but spawn kill.
Less weapons. Every damn weapon under the sun is available to both teams from the start. Why not make it interesting and hide certain weapons around, instead of letting anyone just pick up a rocket launcher, minigun, and three HE grenades from the moment they spawn?
