Looks like they are going to patch the golden lancer out from non-LE owners soon....or at least try to.

Has anyone had any experience with them banning an account for no reason? I completed 2 offers, was waiting on a MCR for one of them (which had been 15 business days waiting on approval), signed in to find a banned message. They still have not gotten back to me a reason why it happened either.
