Ok we'r farming at ongs. We have 3x chars same lvl, lets say 23lv. 2 china with 4 mastery 10lv and 1 euro with 2 mastery 10lv. But Euro char gets more Skill exp everytime. Lets say we both china get 1,4 and 1,5 for ong pt he gets 1,6 and 1,7. Whats with that?? We think that mastery amount decrease Skill points too so we r collecting Curst Hearts. Maybe someone can confirm or denie it?? He and us have no GT or premium. Even cumulated buff is not activated.
