I like the pace of combat myself; you are forced to use tactics like footwork/environment/deception, which makes for better combat imo. You can still get fast swings; you just have to use a faster weapon; don't expect massive greatswords to it. Time to kill is also a non-starter of an argument. I see it being used currently to justify bringing back the steam-rolling of people that helped kill MO1. I haven't read anywhere that anyone was promised quicky ninja alpha-strike kills; perhaps a gun-based game would suit you better. MO2 combat is more immersive, realistic, and tactical. And that's awesome.
It also needs to be remembered that this pace of combat and using physics resolves a great many latency-based issues that were exploited in MO1, like tricking prediction, breaking animations to go thru someones parry that you shouldn't have, and of course, that physically impossible jump-spin pirouette. It also allows people of many different ping times to play together fairly, allowing literally the entire world to play. Considering the one-server-for-the-entire-world mandate of Henrik's, that's important. This is the way it is in MO2, repeated polls have shown more people like it better than bringing the old way back, and that's a good thing. Some people are just going to have to accept that MO2 isn't MO1.
