I also had some issues logging in, but now it's working. Had the error: "Couldn't connect to server."
Well, it is actually really easy to make it for yourself and there are plenty of tutorials in the internet (general hfs editing).
I already modified these .hfs files a little bit. (f.e. removing SP-cost and cooldown of SP-Skills, currently Kai only; making break-offs do-able with every (secondary) weapon; removing bonus ATT of Hero-Mobs etc.) I might release this as well, but of course I need some time to do this for every character.
