Can someone recommend a good vpn or booster so that I can play in the SEA server. I miss this game so much, I’m just going to start from scratch.
Every “ping booster” is a scam. The only way you can boost your ping is by getting better internet or living closer to the host servers. Sorry 
Try picking a server that is closer to your country and see if that helps at all
ping boosters dont help, in fact they sometimes make things worse (not limited to lag and ping spikes)
Ping booster is just another VPN. It doesn’t help improving your ping magicaly.
Dunno about booster but I and some friends use ExpressVPN, and they say it works pretty well
