Yeah, the voice subtitle translations are pretty dubious. I do love that the Devil Hunter's "fire both pistols in all directions" skill is actually called Equilibrium.
For anyone who, like me, finds the Russian voices grating, you can rename (switch around) the Korean and Russian voice folders. Doesn't stick on relaunch, but it's easy to do. I need to see if I can find an ini setting to just make it use the Korean one.
I also used the video posted above to get set up and everything worked fine. Getting 150-170 ping with Exitlag.
