Simple, if the change is so major that it can turn builds into a laughing stock when compared to their counterparts that were able to take advantage of the new change, then anyone who suffers from the same fate will receive a reset for 1 rank.
I posted my ideas above somewhere and I’m positive I removed the possibility of abuse. It also works for only 1 rank which is fine for repairing a build in these cases, and it requires a bit of time and effort.
I don’t know how they do things in Korea, but in the west we have a saying; the customer is always right. You need to do everything in your power to keep your customers happy. Otherwise they’ll leave for your competitors, which is exactly what happened to ToS, and it will continue to happen unless IMC changes their mindset.
Every other MMO I’ve played has offered a plan B when a major change happens on the company’s behalf. This is why you need a publisher that understands the western market, one that will react faster to situations like these instead of just watching your customers disappear one after another. Hopefully something changes before it gets too late.
