Some of the tree of savior features doesnt feel fair thats why i make the following suggestions:
The DPK should just be per account…
lets say you are going after yellow caro antenna which has 0.1% drop chance and DPK 500.
this should mean that everytime you kill you have 0.1% of getting it and once you kill 500 you get it for sure!
this kind of DPK would prevent griefing not create it!
The Upgrade issue would be solved if diamond anvil was introduced to field bosses as a default prize which would make them interesting again or to dungeon #1 dps rank on lets say dungeon 290 or a new Daily 330 dungeon. People would do it alone in order to get it yeap they would but it isnt that easy and the price would drop to a nice range.
