Dual band still takes a persons brain to tell them to pull the trigger.
A skilless drooler can kill a few people by just hitting R1 when a TF beeps at them and tells them to.
That's the biggest difference IMO.
Although true, does usage (or lack of) skirt around the point?
A problem is a problem is a problem (assuming it is a problem). When something is not exploited, I think : "We ll I am glad this is not used by many... " But the bottom line is it the same thing.
The only reason why the ratio is 100/1 is because the guns that can equipment the DB are 4 (LMGs as well?)... whereas the guns that can equip the TF is... well all of them safe from shotguns(? not sure cause I never use it... but sometimes I think I would like to lol)
I agree with the OP. If I were to hate one over the other, it would be the DB because it is equipment on OHK weapons from (almost) anywhere on the map.
