You will always find intersting weapons and stuff with your high level character that can be used to make a new character and with the amount of combination of classes u could spent countless hours leveling and questing 5 or more characters BUT the only issue is that team storage system which allow you 1 item and could be upgraded paying 200k silver, that´s really not good.
It prevent ppl from trying new classes and new stuff…
if there is an update planned to fix that in the future let us know…
Cheerss
