1. Yes, they haven't swapped skills. Well, they changed that ranger's passive isn't a knock back anymore, but SS's power shot is. But I guess you knew this already.
2. The cleric split is still the same. Some minor changes in cleric skills overall.
3. The ranger class is stronger, but because the archer class has received buffs generally. The SS has been changed more.
4. A few changes about meteor for example. Nothing too big.
The balance isn't completed.
