Without for a second excusing the architecture and server locations SE chose that are the source of persistent lag for many players, there are less expensive (and often more reliable) VPN options out there.
A tech savvy FC mate got me set up on a custom VPN built on a Digital Ocean 'Droplet'. That Droplet only costs $5 a month and has the capacity to cover 10-15 VPNs. One other FC mate and I share that Droplet so far. It has made a huge difference for me.
