Following to what Bendak and Shrimps said, they are not wrong in their assessments. And I'm tellin' ya, you're gunna hate it when an RPG or Nailgunner, is able to see how hidden they are around a corner just to third person pop out and shoot a rocket then pop back around. In this current system, at least when you peek, there is a very real chance of you getting your shit rocked. Same with snipers, I can't tell you how often people used third person to head glitch safely/effectively and intentionally. I mean fuck, back with M60 was a viable weapon and we had third person, I was able to post up behind a hill, move up a fuckin inch, bipod up, and mow down Taliban. Trust me, you do not want Third person, and the people above who've given -1's (excluding Harris since I don't know/remember him) were from a time where this was a core strat to use in all fights, including myself.
