there are already people doing this, i've seen them this evening. Easy XP for me I say. I usually don't play crucible and really only started to get the thorn but now I like skirmish as it actually involves tactics and communication. I didn't get it at first but the PvE made me better at PvP by getting better with the movement mechanics and being able to fly over/rain death on opponents while they look around for where I went. Though I must say the number of marks you get is kinda crap, should up it by 1.
