I think they did make a decision to go the action route, hence DA2 (shudder), but they also got the message that was entirely unacceptable to the players who signed onto the series because of all that was Origins. Here, they clearly tried to bring back enough of what we loved there to stiflle dissent while still keeping the action fans who preferred DA2 combat.
They've creatind a real problem for themselves in having 2 games which were entirely different in terms of combat. Now instead of having a unified fan base, they have 3 groups--those to whom Origins was awesome and only needed some tweaks, those who enjoyed the action focus of DA2 and found Origins dull in comparison, and those who enjoyed both styles. Sadly for them, the third group is both the smallest and quietest.
Here, they tried to make everyone happy, and while it's better in all ways than DA2, and for me, a very enjoyable game overall, the combat is basically a middle ground that truly pleases neither the second or first group. Still, they did listen to complaints and the changes that need to be made to make the next game better for those who enjoy tactical party-based combat aren't so huge that they can't be done without losing the action gamers.
It doesn't have to be as slow as origins, it just needs to slow down slightly to a midpoint between this and origins. The tacticall/isometric problem is due to the modelling choice of wanting visible ceilings and realistic landscape. I don't know what the solution is there, but I believe one can be found. Landscape sholdn't trump gameplay.
Bringing back full tactics as in Origins doesn't hurt the action crowd, nor does having the kind of free selection of armor styles with a wealth of style choices. If they don't want to pay attention to that, they don't have to. The lack of real armor choice was annoying and, to me, inexplicable. If they aren't going to let us mod, then they really have to stop forcing one design style on us. Let us gear the way we did in Origins, both ourselves and our companions. And for the love of god, if the clothing looks like something no game or culture has done before, that's probably because it's a really unfortunate look. Kudos to the crafting system and viable crafted armor though!
The 'unrealistic' elements to mage and archer combat seems to be a lingering element of the 'when you push a button, something awesome happens' mindset of DA2, and that just plain needs to go away. Magic and archery don't need to feel like you're shooting guns. If people want to play games with guns, they'll go do that. It doesn't need to be in a medieval setting. There's simply nothing less immersive than a machine gun bow or mages pointlessly twirling and slamming their staffs into the ground or shooting an ice bazooka. They need to let magic be magic and archery be archery.
Bigger and faster isn't always better, sometimes it's just silly and distracting. I'm not in the moment at all anymore when a character does something 'wtf is that?'
They did a good thing by having an effects slider, though. I'm not sure who wants effects to be so intrusive that you can't even see combat, but it's sure not me.
Anyway, thay aren't that far away, they just have to stop trying to throw Origins away And find ways to have all that Origins offered, tweaked to increase the enjoyment of the action crowd.
This whole thing is an object lesson in trying to increase market share. Sometimes massive changes create more trouble than just perfecting the original and lleave you trying to please 2 diametrically opposed groups.
