Dragon Age 2 is an action RPG. I can confirm that. BTW, if you like DKS...you might also like Divine Divinity and Beyond Divinity which are the prequels to Divinity 2. You can pick them up for quite cheap now and can get them from GOG too. Be warned though, these games are just as long and addictive as Divinity 2 and they don't hold your hand either. I'd also say that they have harder enemies at times which means you must employ strategies to defeat them.
The Divinity series are a gem and you'll probably be happy to know that two more Divinity games are planned:
Another Dragon Knight game and another isometric one.
