So, I grabbed this video for everyone of Caspian & Walrus having a little PvP match at Pax east.

In it you can see a clear aim for where they're planning to take combat. (Which is a road I absolutely adore.) It's like a mix between Skyrim(especially after modding combat), DarkSouls, and Soul Calibur. You can see at the beginning of the video, the skills work on a left mouse button, right mouse button combo system. So, different click combinations will lead you down different skill trees much like Soul Cal or, I guess street fighter is a good example too. So, light+light+light=Combo 1. Heavy+Heavy+Heavy=Combo 2. light+light+heavy=Combo 3. Etc. etc. with all your skills.
On top of that, you appear to be able to dodge/dash in all directions. I'm assuming that's a simple double tap of the direction you want to dodge, but it might be more detailed. Who knows. Finally, you have your parry which is shift+click, which is more effective based upon your timing, and blocking of course if you have a buckler/shield. Which, I'm also going to assume has better benefits for timed blocking.
All of these actions of course is going to consume stamina, which needs to be wisely rationed among actions. So, if your battle tactic is to run in spamming clicks, then you'll most likely end up dead. On the other side of the board, you could also die from not be aggressive enough and simply getting pressured, wasting your stam dodging & parrying all the time. So, if you had a large stamina pool, maybe mindlessly wailing wouldn't be a bad idea. XD
Finally, different weapons have different effect on different armors & vice versa. Along with what I believe to be locational damage. So, if you're wearing chain-mail & I've got a rapier... it might be a bad day for you. On the other hand, if you have a war-hammer & you notice my character has an old leg injury, hammering away at that leg could be beneficial to you. Potentially giving me a limp in the midst of battle, or maybe disarming me if you're assaulting my arm.
That's where the beauty of build + gear + player skill would come into play. What weapons are you using? What armor are you wearing? What stats do you have? And how efficient are you as a player in the midst of combat? Are you going to lose your head if I take an early lead, or will you keep your cool & fight for 1 hp comeback out of nowhere?(Which is practically limited to fighting styles like this. As seen in all your popular fighters.)
Even more so, what will you do if mid battle I say screw this, and start throwing fire balls at you? Will you be off-put & distraught by the randomness, or will you keep in mind that there's got to be a limit to what I'm doing?
Then there's 2v1's + Can you handle more than one player at once? Just because they out number you & have better gear doesn't particularly mean they can outplay you. I think the PvP in this game will be anything, but boring.
Edit: Oh, and I forgot to mention that it does appear getting hit cancels your attacks with a stun as I previously mentioned. So if you're coming in with a heavy swing, perhaps my best course of action would be a quick jab to interrupt your swing. Perhaps not. Perhaps I thought it about just a little too long & your swing connects before my jab. Oh the possibilities. :D
