<Contains much spoilers>
I have managed to use a little translation of fan manual and i am quite impressed. Sacrifice was nerfed quite much ( higher mana cost and lower efficiency). I was often dreaming about a spell converting a rage into mana and there it is ! Good Job.We have timeback spell now, altough timeback + sacrifice combo will loose its power by much.
Also i like the new idea about rewards( or however it will be called) like giving additional leadership after winning certain ammonut of battles without lossing any units. Can't wait for english or polish release
