I didn't even enter VoG until I was level 27 I think. I knew the enemies were level 28 so I worked to get gear to be useful. Then you get people coming in at level 24 who were useless. Killing Atheon when half the fire team was multiple levels down was a struggle. But boy did it feel rewarding when you finally got through three or four teleports and finally took him down. Its not the same when he goes down almost immediately.
