I just have been getting irritated with multiplayer lately. To clarify, the lack of co-op on a pure co-op multiplayer is annoying. I'm willing to collaborate with any other users to better the multiplayer experience. My Gamer-tag is "iponce96" without the quotations.
Anyone who wants to add me, feel free. I normally play on Silver with the N7 Destroyer, though I'm not above Bronze. I'll play Gold or Platinum if I'm familiar enough with your playstyle.
