Danger Close - Explosives are already lethal enough. We don't need to have their blast radius extending across the entire map. Didn't we learn from MW2?

Probably because to get the most out of explosives, which are not replenishable as far as I know (I don't use them), they need to be good to justify going without significant battle perks like Focus and Stalker, and players using explosives are unable to use stealth fully too.
As for quickscoping, it's not unknown for weapons getting kills outside of their optimal ranges. I used the AN-94 in BO2 as a fully automatic sniper rifle since it barely had any recoil, significant damage at range, good fire rate and SMG-like fast reloads. Guess you never complained about that though.
