This first part - griefing - only works as a Warlock, but, it's still kinda useful.
If you've ever tried to farm the demons in felwood or azshara (as I have for Demonic Runes - part of my Robe of the Void pattern) you know about the idiotic chinese farmers who try to kill steal anything.
I've succeeded in getting a bunch of them dead, and here's how:
Follow them until they start attacking a demon. Let them get it to 80% and BANISH the demon. They might keep trying, if they do, rebanish it... usually they'll go on to another demon. When they do, banish the SECOND demon.. the first one will start attacking them again. If you're lucky, they'll be fighting a few demons now, and you can banish some random one far away, releasing your second banish, and leaving them to fight more demons than they should be.... dead chinese farmer (keke lala ^^!)
Weapon Skill Ups
Really simple and obvious. If you're a warlock, it's easy.. but if you have a warlock friend, you can try to get them to help you.
Warlock finds a lone demon/elemental, casts Curse of Shadows, and Banishes them. Start whacking away with your melee or firing away with your bow/wand/gun... I've gotten staves/swords/wands to 300 on my warlock this way, without EVER using them almost... but I do use them in pvp sometimes, so 300 on them is very important.
Not too amazing stuff, not expecting any benefits like extended membership, but still useful.
