stone of destiny have the promblem that lose experience-skill enchant-passive skill enchant (they cost 100 billion+) dual to main service service was the perfect solution but if can't work then the dual separation with option items and quest transfer to dual class. if items keep them main class really that service help only ppl that want create box high lvl in other account so can log them both no reason someone to change dual with this way when exist libra.. people pay thousand euro and many billion to buy items like agathion ,shirts,brooch jewel and must be possible to keep them.
