I'm pretty sure offensive emblems are actioned like just about every other game, it has to be reported by the community. I doubt they have dedicated people who spend all day looking through emblems being created, if you see something offensive you don't like then report them via the in-game option to draw attention to them.
Quickdraw works just fine on SMG's, maybe the effect is reduced on AR's .
Might also depend on perks? There could be a cap or sth for each weapon type, which wouldn't be a bad thing.. If it is really glitched, expect it to be fixed soon enough and pick up another weapon config for the time being.
Never had any issues with quadrotors so far. There could be a limited amount of killstreaks active as in the previous black ops?
I hope that issue on AGR is a rare case, I didnt have any issues with it. Maybe try to manually position it somewhere, away from your location.
Seems like silencers are working as intended, since a silencer slows down bullets reducing the impact.
Hit detection is the same as in previous versions from my experience. Maybe this issue is related to bad connection.
IW, Treyarch.. Do they have to be compared in every topic? They are both very good i'd say.
If one of them would be better, does that mean the other one is pure crap?
