Slight increase in turning speed. I know the time to make a 360 turn was increased from 0.2s to 1.2s in order to reduce the ugly-looking 'spin-stab', but I think it's made it a little too hard to turn and face oncoming opponents even if they're only approaching from the player's side.
I would suggest you try a mid-value compromise, perhaps 0.6s or 0.7s? I think this would still prevent the exploitative spin-stabbing but would give players that little bit more maneuverability in melee combat that would improve their experience.
It's not a major problem, I am loving the new melee elements (the overhead stab is a nice challenge to get used to) and melee is still very fun. I'm just thinking for the more competative side of the community who will be playing in very melee-intensive and individual-skill focused environments (e.g. the upcoming European Cup Tournament) and I believe turning speed is something really important to get right in order to allow for competativeness to flourish.

I don't know whether it's true but to me it felt like running speed was slower. My problem with this is that when someone gets engaged in a melee fight it's quite hard for them to retreat from it because they can't escape fast enough without getting backstabbed. I know it's cowardly to evade an enemy whilst in melee, but it should nevertheless be an option to a player.
It could infact just be the turning speed reduction (mentioned in point 1.) that is having this affect and the running speed is actually unchanged, someone will have to enlighten me on that, but just the general feel that once you get into a duel you cannot escape it seems a bit limiting to a player. I hope that can be addressed.

Please don't take these critiques as my overall judgement of the DLC. I am, in fact, absolutely loving it! You've really nailed the Napoleonic atmosphere and no doubt it'll entertain me for many more hours to come! Cheers.
