1. Yes, all of the Divinity games have been using a classless system, but [in my opinion] players should be rewarded for sticking with one particular tree. They should be rewarded with a very good and unique skill that is on top of the talent tree [because people who mix skills tend to pick up only the best ones from each tree which is kinda unfair].
Unless one very evil game programmer decided to make it impossible for anyone stupid enough to invest in only one skill tree of course
Maybe this sounds crazy but I liked the mixture of worthless and powerful skills next to each other. Forced me to consider very carefully.
