The only thing new and fresh Divinity 2 bought was the buggy stuttering engine, the same engine Piranha Bytes and Bethesda (and even some Indie devs) used to creat perfectly stable and WAY better looking games.
There was nothing revolutionary about Divinity 2. I enjoyed its story, NPC's and funny writing, not to mention the great voice acting. But everything else was poorly done, a terrible console port.
Borderlands was generic but it's still a perfectly done Diablo conversion to FPS genre with fuckload of guns (which work as advertised). Basically it removed the pointless story from Diablo and worked on making the combat interesting (which Divinity 2 fails at).
