Keep it the way it is.

Combat in Xsyon is hard but simple and in a way similar to what you get in the real world, you have a big stick and you need to beat the crap out of your target before it does the same to you, this kind of combat takes skill, timing and a lot of luck.

Probably going to upset a few with this, but from the sounds of things most want a "fire and forget" combat system, or as I call it the lazy turd combat system, the kind where you get a bunch of skill combos, keybind/macro them in rotation, select your target, then hit a key and sit back and watch your toon kick 9 colors out of the target. No skill, no luck and very little timing required, and not to mention boring as hell.
