Its kinda crazy! Its like a 40 man raid again!
Easy bosses (often with just one mechanic)
1/3 of the people do all the work
People blatantly don't follow directions
Baddys get the loot
AFKs and Laggers
The list goes on, its like being in Molten Core again.
In all seriousness, I wonder if that's why I like it so much. XD
