OP your best bet is to take note of the people who are glitching out of the map, go to the battle report after the round ends and then highlight their name and click on the small triangle with the exclamation point in it to report them. Select report cheater and wallhack and then type what they did wrong. The community has been very vocal at reporting the various map glitches to DICE and we are all eager for them to release the fixes. I've only had to leave a couple of games where people went out of the map since nobody was actually playing the objective, just trying to kill the glitchers. It is frustating as you have found out.
