Disabling fall damage. It isn't a bad idea at all. I believe fall damage was in purely for the reasoning that the /warp system is actually quite new and there would have been no other way to die, without it taking a while.
Mainly to get you back to the building once you fell because there used to not be level warps. Some of the levels I made were designed with fall damage in mind but it's not an issue if removed. The real issues come into play with glitched promotion ranks by falling into the void and the entire chat would turn into all new players asking how to warp. Unless Cyp wants to encase everything in a box of barriers so people can't boost their level and break their rank, it shouldn't be removed. Edit: Plus it just makes it easier to catch those cheating with fall damage on and no multiverse auto tp portals
