I dont get people's complaints with OMA. Its not a glitch, its not something that YOU yourself cannot do. It needs no patch as it is not broken, it is exactly what the dev's had in mind when they made it. Its a perk, takes away one of your 3 perk spots, and it also removes your secondary, so its not overpowered.
I really dont get why people whine so much about this perk, maybe because if they did patch it, it would not affect me as I only play SnD and never switch more than once anyways.
I cant see them patching it, and if they did I cant wait to see the rationale.
