For both Dragon Age games, combat was naturally a huge feature. Your missions and quests usually involved a battle at some point, so the way that the games approach fighting is important.
Dragon Age: Origins was fairly standard tactical fighting. You directed your party of four around in the fight, guided by their automated tactics and your intervention and then used abilities and your weapons to overcome enemies.
Dragon Age 2 honestly follows this fairly closely. The fighting has more of an action feel to it, which to be honest, I liked. It'll be perfectly subjective, but giving a little more direct control to the fighting gave a real sense of power to rogues and warriors. And, if someone didn't want to play it as an action game, it was certainly possible to pull the camera back, pause often and play it in the older fashion without too much of a change.
That's not to say that the combat didn't end up being disappointing though. Anyone who's honest with their review should have noted the omnipresence of waves of enemies. I swear, local gangs must mug kings every night to be able to fund dozens of skilled mercenaries to throw themselves at you. You can also insert a few jokes of your own about the common bandits taking lessons in expert rappelling just to surprise you.
Every fight was the exact same. I think I can even say that literally. Every fight consisted killing ranged fighters/mage, then the grunts and preferably the leader, once you got some breathing room, all while watching the waves of reinforcements for any priority targets. It didn't matter if it was spiders or bandits. All that it impacted was whether I was fighting a spitting spider or archer. There was nothing to any of it. Just cardboard enemies with different name tags.
There were no tactics, beyond spamming abilities and praying that your mage was left alone. Positions didn't matter, because enemies would literally come out of thin air to flank your ranged fighters. Cooldowns made healing impossible, while heavy limits to stamina and poor squad AI meant that you were out of energy before the first wave was dead.
Compare this to Dragon Age: Origins. Yes, you often fought darkspawn, but there were golems, bandits, rogues, demons and mages and they all required different strategies. It was possible to actually position your group strategically and plan out fights.
The combat, while actually making a nice step forward in its appearance, took a flying leap backwards in the actual implementation. If a rage demon and bandit fight the same way, then something is very wrong.
