I don't really have any balance things I want to change, but I would love to add some attachments to some gun types. I really like the holo sight and despise the RDS, for example (I'm weird like that). I wouldn't mind seeing the holo being added to shotguns and etc. Just an example.
People keep on saying this, and personally i dont think it would be as effective as it sounds. If Treyarch did this, the SWAT-556 would be just like the M8A1, except 3 burst instead of 4 burst. Also, if they did this, the M8A1 would be better anyway.
It's better to have two very similar guns than to have one completely outclass the other imho. And at this point, there's no reason to use the SWAT over the M8A1.
When i posted that, i was thinking prior to the patch. SWAT is better. Ive been using it before the M8 anyway.
