Why box on Icecrown

What is the use letting people box in pvp on a server that is always over populated? I assume to make whales happy like always. Anyway its pretty lame seeing a ball of caster nuke people in one his. Then again I guess allies have to do something to win :D

If the server is always overpopulated, wouldn't it be easy to overcome a person with 5 characters?

You're just mad you got ganked by an equal level player, while for you to gank somebody, they need to be 2 levels or more lower.
