Ahh it's you. Been a while hasn't it? We WILL finish this.
Just you wait.
Yeah I like thel vadam. He's cool and he's one of the few elites who doesn't act like and think like a zealous religious arrogant bastard. But he can't win against master chief. Arbiter may be cool and may have gone through a lot of epic huge battles and to survive them means he's skilled, but you guys forget the crappy armor he wears. The arbiter's armor since its old, has MUCH weaker shielding than the mark 6 armor chief wears. And I'm not completely sure at all, I'm just making a guess I might be wrong if I am correct me, but I don't think it enhances arbiter's physical capabilities. So chief has the advantage on this one.
And also chief has killed many elites with the same skill and abilities as arbiter AND has fought longer and against stronger forces than arby. Realisticly guys, chief has waay too many advantages, he would win. But I know it wouldn't be an easy fight at all. Chief probably would end up with a nice new big scar on his chest to remember arby by.
