My ping isn’t changing. The ping that mudfish displays is around 50ms but my CMD ping requests don’t change at all, my ingame ping isn’t reduced as well.
While playing the game with item only, could you please check How do I know if its working? section whether there is some network activity depending on the game play? If not it seems I need to update the game item of mudfish. 
By the way, as of this time of writing, the best node Mudfish is able to find is at 150-170ms from PH to SG. =(
Not sure it’s still same. Could you please check it again? When I checked your RTT information, I don’t think it’s Mudfish issue.
