Would someone please give me a summary of what has changed for this edition?

Okay, because of Warhammer Quest: Cursed City I have been collecting a Soulblight army for the past few years. The reason I say collecting is because I still have everything in boxes and haven’t built or painted my army yet.

Now that this new edition has been released I am seeing people dump a good bit of the Battleforce boxes and other items on EBay. I saw that there were a good bit of models that had base sizes be changed, which is absolutely fine because I haven’t built any of my models.

My question is, other than base sizes and the few things from the new Deathrattle box, what else has actually changed and is there a good place to see a summary of everything that has changed?

Or did I just waste my time and money these last few years collecting a Soulblight army that I can no longer play?
