The fact that they can be 5-boxed is actually a joke. Don't understand why blizzard didn't buff them with the gearupgrades throughout wotlk. A city/faction boss should require a huge raid. Now any dork that walks by farts and they die. I even saw a dk the other day who was soloing him (killed him though).

Apart from that it's fun to do as a boxer of course, and you should go for it. But it doesn't make much sense to me that it is possible.
