In a nutshell:
Theres a Korean streamer on central 4. This brings in a LOT of players from that region.
The major issue here is that the players pings are so high that they basically skip around and are playing on a whole different level. Due to the high pings they can skip around (what seems to be lag for us) and on their end not be lagging. We have had several scenarios of groups fully armored and armed get defeated or escape by naked or cloths with low to mid tier weapon
Not requiring a certain ping (response to and from the originating source) contributes to unfair game play. Asia/Pacific while should not be restricted entirely should perhaps be sent to west coast servers if any, or join eastern or central servers i they meet a required ping. I am not sure what type of logic is required but the game is not suited to handle this scenario if requiring a certain ping is out of the question.
PS: All of the people who grief and belittle them for joining a US server has issues. I see nothing but rude, racist things in chat toward them. This is not a skill issue or any other issue less a network problem.
