That may be true for you, but that was hated by most players. The speed of DA2 was over all seen as a problem; DAI adds much needed weight to combat. With that said, the staff animation is still silly.
I personally loved the animation in DA2 for the Mages as it finally made sense that we'd actually use that blighted staff as a weapon, instead of just pointing it feebly when enemies were up in our grill like in Origins. And I'm of mixed opinion about the speed, as on the one hand, spinning it like a boss made your Mage seem more athletic, but at the same time, it made the staff look like it was so light it should shatter with the force you slammed it on the ground with.
That being said, I kind of like the more realistic sense of weight behind the weapons this time around. Daggers weren't so bad in DA2, nor were Archers, but two handed swords was simply ridiculous given the sheer size of some of them. Of course, two-handers being as slow as sin were my major gripe about them in Origins, but they went way too far the other way.
Actually, while it'd be a lot to ask for the devs (not to mention, a complete pain to implement), it'd be cool in future games if we saw different mages using different combat styles with their staves, depending on whether they had any formal training or not? After all, I could imagine a bookish Circle Mage isn't going to have as much finesse as an Apostate might have in melee combat, while the Apostate probably will lack some of the skill a Circle Mage has when it comes to casting?
