Ok first off this requires you to be on a pve server of course abnd it requires one friend or more if you would like but one at LEAST.
First off you need to get your enemy to flag(for new players you do this by typing /pvp, r you attack a flagged enemy of the opposing faction) This is where your friend comes in. He must make a character on the opposing factions side ( so if your horde he needs to make an ally vise-versa)
Now you must decide where you want to go pvp. (this depends on your level i recommend levels to pvp in starting zones) THIS CAN NOT BE DONE WITH NIGHT ELVES UNLESS YOUR A 60 HORDE DRUID/ROGUE BECAUSE YOU MUST GO THROUGH A MAJOR CITY!
Now your freind makes whatever race that is in the area you are gonna kill.
After your friend has made his char he should go to the next town after the starting place.
Humans- Goldshire
Gnomes,Dwarves- Kharanos (sorry if spelled wrong)
Night Elves- Dolaran
Orc,Trolls- Razorhill
Undead- Brill
Tuarens- Bloodhoof Village
after he is at the town you must meet up with him with your character and have your friend flag him self. (Don't kill your friend when he flags or it defeats the purpose)
Now have your friend run around asking for buffs. Since he is flagged when someone buffs him they become flagged and that will allow you to killl them.
thats it! have fun ganking and and watch out ganking because some people do have high level mains! =D
I apologize in advance if this has been posted before i have not seen it therefore i thought it would be somthing nice for some of the new players.
