I pray to God it doesn't. In my opinion, I see two outcomes.
Doubtless. As mentioned, I dont mind if its genuinely hard as balls to do like it was in BO1. If I got taken apart by a mobile sniper in that game, I had to take my hat off to them. Didn't happen often though, as the snipers were tricky to handle.
Other games, I'm kind of with Drift0r on his BO2 in depth assertion - I'd hesitate to say OP, but I would say deffo a little too competitive outside of their intended ranges...
As opposed to the unlimited range of ARs and SMGs? And ARs get Stalker and Quickdraw benefits to make them faux SMGs so it's not like sniper rifles are the only weapon that have some minor ability outside of the intended range. There was no need to snipe in BO2 when the ARs can snipe across the map anyway.
Unlimited range sure, but considerably increased TTK especially when the need to burst off shots is factored in. But all this is moot, the proof is in the pudding. Which CoD is best known as an out and out snipefest? Quite. Deffo the easiest title to snipe on, even I can do ok with a sniper LOL.
Again, I would hesitate to say OP as ARs/SMGs still have a faster TTK in their intended range, if the sniper misses they are stuffed, and the Ballista requires more precision/luck to get an OHK. I'll also happily admit that pretty much any clip dredged up to show how OP'd snipers are, even from BO2 *sideways glance at Thunder* are far from the truth. Most involve a horribly off-the-mark killcam that is touted as the definitive evidence.
I've seen enough killcams showing a sniper not even fully scope in when they clearly had to know not to trust killcams lol.
