I only pay $31.95/year with the 20% off discount. Normally it cost $39.95/year.
VPN is going to affect ping no matter what, if you want to decrease ping, you could try WTFast. For me, the VPN only increases the ping by 10-20.
In league of legends, my average ping without VPN is 80. Using PIA, i get 90-100 ping.
Private Internet Access is pretty good, claims theres no logging - which im pretty sure is true, and it is decently fast
