Watching the trailer I am liking what I see with combat. I think if the combat can become a true melee/magic FPS style, you will not only garner MMO fans but fans of series like Mount and Blade (CRPG mod) and Chivalry: Medieval Warfare. Being able to real- time parry, thrust, slash, kick to break blocks, shield slam, judging distance and swing speed of your opponent and having to aim your bow shots and spells while having stamina consequences would be fantastic. Marry this with stat allocation and a persistent world it sounds like a blast. I think a lot of people felt this was what Guild Wars 2 was going to be but it still turned out to be a game bound to attack ability hotkeys with dodge roll thrown in so not quite the realistic melee action fans were looking for. It will be a refreshing break from the standard that has basically been in place since EQ of auto atk and hit ability buttons which is becoming boring imo.

I don't think the combat will feature that many abilities. I am expecting real time blocking, dodging, attacking, and shield bashing. However, I would not hold my breath for parrying or kicking or anything like that. It is an MMO, keep that in mind. Some things just don't transition well into the MMO space from SP games or match-made arena-esque combat (like Chivalry: Medeival Warfare) games.

While the combat will be much more impressive than usual MMOs, it won't be like what your fully describing. As much as it makes sense to have a dodge and work that into combat, there won't be anything like there. There isn't a parry(as far as we know), and we don;t know if we can break blocks or not. Not to make it sound like the combat won't be awesome, cause it will, but it just won't be fully like you described.
