Anybody who says...
...that Dragon Age 2 has been dumbed down, suffers of a severe case of unfounded bias. The prologue's final fight against the Ogre - it took me like 5 attempts to finally understand how much more micromanagment I had to do, in comparison to DA:O. At first the fight seemed borderline impossible with the very limited skills and consumables I've got at my command. It took some banging my head against the wall, until I got it down.
Movement is much more important now. Thankfully it's a lot snappier too. Like moving Avaline out of harms way everytime the Ogre gives away his next big attack with an animation. Grabbing aggro with Hawke (going 2-handed warrior with him) from as many adds as possible. Having Bethany throw in an AoE Firebal into the fray and while having Hawke back away quickly. Kiting when no healing spells or healpot cooldowns are available, when in a pinch.
Healing is a lot more tactical now, since both healpots and Bethany's heal (she's only got access to one heal spell) are on a lenghty cooldown timer. It comes down to a mix and match of grabbing aggro, kiting, evading the Ogre's attacks such as Hurl and Charge and Stomp (or so I dub them), as well as setting up my own AoE attacks without causing harm to my group.
Can't wait to have access to more skills and especially starting to synergize with skill combos for maximum dps. Probably going for a group set-up with an offensive Tank (Hawke), a Rogue (prolly Melee for casterprotection) and 2 Mages going for Support/Heal/Crowd Control first. Should give me enough wiggle room to deal with the harsh difficulty and challenge of Insanity.
Combat is definitely more challenging with an increased emphasis on smart and reactive movement, rather than being a tank and spank system like DA:O, which mostly relied on decent preparation (potting on cooldown, while every pot-tye was on a own CD and a short one at that, made the game quite easy). Classes and specializations also feel a lot more distinct. With two-handed Warriors dealing AoE damage with every strike and sword and board Tanks really being mitigation tanks.
Seriously - get over yourself. I got a great first impression. All I needed to do is bang my head against the 'Insanity Wall', until I saw what it was about. It's great and a lot more involved than DA:O's mechanics are.
