Fun from ganking
You can acquire much more fun from ganking when you do it yourselves than others do it for you. A player with well skill and rich experienceis able to take on several less-experienced and geared players, so even if you have numbers and gear, you are not insured to win the fight.
No name tags are floating above someone’s head, so the only way you can recognize them is by their race or that you hover your crosshairs over them and read the description of their race to see if they are gray, blue or red. You pay close attention on colors, because blue on blue crime does not occur.
