290ms is actually quite ok, you can give VPN a try but it won't go much lower though, maybe 10-20ms lower.

been using Battleping almost a month ~ very good so far, ping average at 250-290 ms
but i think that is not a actual number, in actual i think far lower than that i guess,
very smooth gameplay experience with battleping even in gangbang PVP.

RM20 for 30 days lol....
u can try first... login with battle ping... trial version will dc u from game every 20 minute.

Only when it spike, my ping is usually around 260-290, so if it's in that range there is no lag.

i suggest u try first, if u like it get the voucher from offgamer site.

i usually use "connection 2" with "chicago server 3" for Battleping VPN setting

Battleping subscription work on timecard that you can get from offgamer website, you can download battleping from battleping website. I use to use it but for some reason if I use battleping now it won't let me load the character selection screen and I was too lazy to troubleshoot. Since my ping without it is fine.
