When torrenting, it's often more convenient to use a proxy in the application itself instead of PureVPN. With the addition of a SOCKS5/SOCKS4/HTTP proxy it would make torrenting with PureVPN much easier. Several competitors offer this for free with their VPN and PureVPN feels like it falls behind significantly due to not having this feature.

purevpn without socks5 is useless
