using it now. takes a while to figure out stuff (not as user friendly as I would like), and LOTS of servers, some of them not stable in peak hours (7 to 11pm), some are. need to find your own sweetspot server by experimenting.

tried WTFast and battleping, both get me to 150-200ish on oceanic, mudfish also did the same.

and yes, it is by FAR the cheapest solution of all. just need a hellot of time to optimise the experience yourself
