I have thought of many options to suggest but i just want to share this because for me this is the best option....
REMOVE/DISABLE VIP Hats from gaining MS from 2set effect of VIP parts so that people will be needing "expensive" VIP gloves/boots + VIPeyepatch to gain MS set effect and "poor" people like me can easily discard VIP hats because there are a lot of options to choose from the new set effects of other costumes. This is a fair option because people can choose whether they want to use 3/4 set effect of BWL/BWS/WR + Bach pa for damage or BWL/BWS/WR + vip gloves/boots + eyepatch for additional MS..
I think it's fair for people who have VIP gloves/boots who donated or bought them at high prices to complain because these items will be worthless on the upcoming updates if their effects will remain unchanged. Just my opinion i really wanna help you guys on this matter.
