Actually, Shadow/Assassin is grossly OP and needs a major nerf. And judging by Bioware's track record, there won't be a minor nerf, both class types will get the touch of death like Sage/Sorcs, Op/Smugs, and general hybrid builds before them. As stated by the lead dev, when enough people cancel their accounts and state sent/mara or shadow/assassin the reason why, Bioware will react. Example: Teams of operatives going around making people quit.
