Great question! Similar to something i've asked before, then learnt about when running other game servers. 1 thing i can tell is KR mmo/online games in general have no ping delay allowances, Due to KR players within a range of 5-40ms ping, so no allowances are needed. But as we are in a range outside of KR of 20-170ms they are needed & not usually added, Final Fantasy XIV at release was a JP game that made this mistake then added a 200MS ping allowance (claimed by the FFXIV team, Personally i'd say its more like 150ms but this is just an example). Also a factor is the "grid" of open world, needing to allow for damage on 1 grid crossing into another grid, causes delay & issues in game. 1 of the reasons why KD causes people to move around, constant issue in BDO that keeps popping up. makes me wonder about its coding for this. This was bought up for Kakao to answer on the old forums & they never got back. I hope This time Kakao Takes the time to answer your question!
