Wrong. Those aren't combos they are status effects. The Combos in DAO included the giant storm (Fire storm + lighting storm when arcane might is active), Really Bad Dreams (Horror a sleeping foe), and other unique combos. It also had a few semi-generic combo's, mostly shattering petrified or frozen enemies with crits or backstabs or stone fist.
DA2 had 3 combos, 1) apply Warrior effect (Staggered) then let Rogue or Mage use any of their abilities that require stagger, 2) apply rogue effect (Disoriented) and ditto, or 3) Apply Mage Effect (Brittle). They were very generic and rather boring. I liked in DAO you had to do certain abilities to unlock the combo, as compared to DA2 throw and effect on them and done.
As for Maria's point about DA2 allowing Warriors and Rogues to participate, I agree with that, but I feel they should maintain more 'specific' combos while doing it.
No. You confusing spell combinations with combos. 2 different things. Combos are appliances of attack to control and do more damage to enemies. It's not what dao had, which is the enhancement of effect of spells based on other spell. The issue with dao it that it was too dependent on mages for it and it left little chance for other classes to take part in it.
With dragon age 2 the combo did far more then what dao did. Staggering reduces enemy defense and attack by 25%. Staggering reduce enemy defense by 50%.Brittle/frozen increases critical damage. Abilities also increased in attack power based on the state the enemies are in. Added, the chances to use it was very active due to more then one class where able to do then and more abilities can cause them. Some abilities had addition effect as well like confusing enemies and concealing allies.
DA2 combo system was far from generic , it was extremely flexible. In fact dao system was way more generic.
