There is and always will be a couple overpowered weapons. The thumper's popularity is dying down and I haven't seen it be abused for a while. And the 1887 akimbo was nerfed in case you didn't notice so it's not as cheap as it used to be, as for the noob tube it was nerfed too and now it feels like you need danger close on to replicate its dammage before. As for the intervention its not overpowered it's just people that have too much time on their hands and they get lucky with their shots, besides, if you've noticed many of them take four shots before they hit someone. The chopper gunner should be taken off because its not every match that someone calls that in and if I remember correctly it has three flares on it so it may be a pain but if you fire enough anti aircraft missiles it will be taken care of. The G18 akimbo and Vector rapid fire are growing in popularity but if it really becomes an issue infinity ward will nerf it too. And once they do that someone else will probably find another weapon to abuse and then the other quick XP noobs will hop on the band wagon and use it untill its nerfed and reset cycle.
