Divinity II: DKS - Review @ Strategy Informer

This review at Strategy Informer actually focuses on the differences between DKS and the original Ego Draconis release, rather than looking at it as a whole new game.  The score is 8/10 and here's a quote:

Extra quests have also been added in here and there, some of which seem to be padding but you could also argue that it helps balance out one of the games major problems - choke points. This was probably the single greatest flaw in the game, and in some instances a gamebreaker. For some reason, enemies that were a higher level than you in Ego Draconis would be more powerful than you than one would normally think considering that we're only talking about a couple of levels here.
 
Whenever you entered a new area, the enemies would often be a level or two above what you are, and given the games love of trying to overwhelm you with numbers, this would then create 'chokepoints' - sections of the game which were an incredible slog to get through. Eventually, you would manage to scrape enough experience points together to level up and even the playing field, but it was certainly very annoying to say the least. Thankfully, things have been improved dramatically on that score.
