The melee action in the gameplay trailer actually looks pretty neat.
It looks passable.
Though, the key question is always how's the skill trees going to be like. They've never been particularly good in Dragon Age games in terms of either customization or options (Especially for non-mages where you got far less "Combo" skills... Or skills at all)
Since the trailer only shows early game footage, we only see the bare bones combat (Spamming attack and having 1 skill available). We don't know much like, could we spec this Rogue into melee or ranged? Poisons and stealth? Any cool Prestige classes to unlock? etc. With also how does this compare with companions? (All the companions in this game have unique titles, does that mean they'll have unique skill trees? Or will they all have the same generic ones the player has?)
To say nothing about other classes, like the Warrior and Mage archetypes (Will there be any others?) as well as how overall combat will feel like when it comes to making a party, especially with the 2 companion limitation (Used to be you could bring a Warrior, Rogue and Mage with you to create a balanced team and then your PC will be a second of one of the archetypes. Now will you be forced to get the 3 different archetypes with your 2 party members and your own character to create a balanced team? What's the difficulty like? Will you need a Tank built Warrior and a heal focused Mage like in prior titles?)
Also, what will the non-combat gameplay be like? Is there much to explore? Is there reasons to explore? Can you talk to people? Are people worth talking to? What is equipment like? Is there much variety? Enchantment? etc.
There's a lot of concerns I have about gameplay. But I guess time will tell once more information is released.
