Yeah TTKs have really been slowed down overall for AW. It's almost like Sledgehammer saw all of the (slightly confused) cries about Ghosts having "fast" TTKs and thought they better be safe than sorry lol. Even Ghosts' were slower than average when compared with older CoDs like MW3 and BO1...and FAR slower than games that featured Stopping Power, because it was such a commonly seen perk and you might as well count the higher damage as standard.
When all of the lag issues in AW are fixed (if at all), I think I'll really enjoy the slower TTKs. I'm all for skill gaps, and promoting accuracy and gun skill...the lack of any overly strong weapons in AW (even from the start, hats off to SH for that) helps out there too
