Something that is really disappointing is seeing some of the reactions... some are acting as... y'know
Stop complaining soooooo negatively! It is OK to express oneself as one sees fit, but always bearing in mind that we are talking about an artwork here.
And, as such, many people spent a lot of time on it, they put all of their excitement and dreams into creating it, for others to enjoy it. So, could you please stop for a moment and understand all of that? If you don't like what you are seeing, fine. You have many options. Nobody's forcing you to buy the game. If you want to speak your mind (and want people to listen to you), just do so... but with respect for all the work these people have been doing.
I think they are being so great just by showing us all of that stuff that normally I'd expect to discover in the game, so why not appreciate it? Are *some* (always talking about some, ofc. Most of us aren't that negative about every single d*mn thing!) so self-centered that they believe that everything has to be made in order to please them and only them?
Again, I'm not saying you cannot express your opinion, of course you can! Sharing opinions is what makes this platform interesting... It's just a general feeling I'm getting like all some like to do is to complain. Maybe they feel like the world/the game/BW/etc. owes something to them? Instead of appreciating what they're given? Can't figure it out.
Sorry, had to comment on that 
On topic: I really enjoy everything they've shown so far, I think they are really making a big effort by giving a wonderful game to the fans, and IMHO it shows! 
To all the people out there complaining non-mages get those "flashy" abilities that are unrealistic somehow, I'd say there are many core abilities in non-mage classes' concepts that are unrealistic by themselves, at least by real life standards
So why not enjoy it? This is a fantasy game, after all. It doesn't have to be realistic, (IMO it has to be imaginative, creative, etc. but that's just my opinion) for realism we have real life.
