No Intentional FF/TK'ing:
Yes this includes punching and/or kicking teammates (regardless of their armor level)
Yes this includes wounding, killing their horse, regardless of how much we hate horses
No Ladderpaulting:
Yes this means the enemy as well as teammates. Just don't do it.
No Glitching/Hacking/Exploiting:
Yes this means using your ladders to go outside the map. Knock that off.
No Delaying:
Yes this means if you're the last guy alive and running away without attacking, you will be kicked.
No this doesn't mean you can't play your class. If you're a HA and have arrows you can kite and shoot.
Yes this means as an archer you can kite and shoot, as long as you're actually engaging the enemy. If you are just running for long periods without turning to try and score a kill, you are now delaying.
Yes, if it sincerely looks like you're using tactics such as running around a corner and turning for a surprise counter attack then that is acceptable. Flat out hiding is not.
No Douchebaggery:
This is a catch all that includes, but is not limited to;
Racism in any form
Aggressive harrassment/trolling of other people.
Excessive griefing other people after being told to stop
And as a general rule if you're being a complete dick/asshat/douchebag you may be asked to knock it off. Failure to do so can result further action. There's a difference between general light-trolling and gamer humor and just generally being an unpleasant asshole.
