Healing.
Not sure have to play the game to find out. I do like the move to more thought out gameplay rather than "lol i can just heal everything so i don't need to worry about tactics and ignore the enemies abilities". I find it amusing to see the same people who are complaining the game seems less tactical are also complaining that healing has been removed making the game perceptively harder, good job there with the thinking.
8 Abilities total.
Initially i didn't like it, i'm still not sure that i do. The argument that it makes combat more tactical and you have to plan ahead is valid... However how does one plan ahead with what abilities they are going to use if they do not know what the enemies are going to do, is it assumed there will be some trial and error involved or that you will learn which enemies in a pack are going to do certain abilities? I would have preferred to have access to all of my abilities, again need to play to find out exactly what i think of this.
Cannot allocated attribute points yourself on level up.
Don't care honestly. In all of the games i have played that allow it i have allocated the points correctly according to the class and spec. In this iteration of Dragon Age when you choose your talents they also come with bonus attribute which is relevant to the spec. So for me literally nothing has changed but there is less for me to do on level up which i am fine with. I'm not one of these people that want to make a high intellect warrior because reasons.
For things like graphics and characters it all looks good to me. Can't wait to get it in my hands to see how everything comes together and how the changes have really affected the game.
