I was contemplating rerolling a character when I realised that spending skill points in templar heals and staff heals was a waste, you can only have so many on the bar but then I realised, I have spent so little points and I read that getting points later is pretty easy. Besides, I have fallen in love with my character. I have died SO many times between level 1-6 experimenting with the combat (I already have an achievement for dying so often, muahahah), worth it though, I know some jewels of experience now.
Surprisingly the game runs great on my very average system with full settings.
Yep as GazWorks mentions, i think it's lvl 15 where this "feature" unlocks. It is similar to GW2 where if you switch weapons (this would be a hotkey, not you going into your inventory and swopping it manually) you get a new [customizable] action bar where you can place different abilities. I fully expect to have a staff vs. sword+shield thing going with a Templar.
I rolled a Templar and a Nightblade , and so far Templar my favorite, despite me turning it into some sort of sorcerer at this point (i hardly use my stamina abilities, might consider getting a bow or staff). I played a DragonKnight and Sorceror in beta, and they were kinda "meh" or shall i say, prone to being stereotype playstyle (2H Melee and Ranged Magic User ) whereas the Templar seems to be alot more open to diversifying ... i can see it quite possible to be a Templar in Cloth and being a pure healer OR a Heavy Armor Melee Tank OR a self-healing hybrid.
The Nightblade seems to be the Necromancer (Poisons/CC/Dots) vs. Dual Wielding Assassin vs. Bow type of DPS class, but still felt more flexible in terms of where points go and specialisation.
I'm sure the Sorceror and DragonKnight have some interesting paths to go down, but i didn't feel it, it felt somewhat straight forward to me.
A different way of putting it, i felt you can quite easily gimp a Templar or Nightblade due to alot of weapon/armor/class abilities looking like they can work together, whereas the other 2 classes felt kind of obvious where you should focus.
Also just a big tip for the people that didn't play the older betas. There is what they call "Starter Islands" for every Alliance. They no longer "force" anyone to go to these islands. So when you pop out of the tutorial you are a in a big faction town which is probably like lvl 5+ with all these quests available (so you can just start questing from there) . However, if you do read your initial quest text you will get a lead on traveling back to the "Starter Island" of your faction, which is a lvl 3-6 area. I think alot people miss that and go straight into the city and get their arses handed to them for a few levels

.
In the older betas, you were placed on this island straight out of the tutorial and had to finish the main story on the island before you could go to the mainland. So i suppose they felt this is a bit too restrictive and linear and made it optional.
Either way, some starter islands are better than others, but you get a good start with gear and skyshards/skill points by going there.
