I was gonna post this two days ago, but it got bigger and bigger and eventually expanded into a project. The results of which can be seen here.
In short, I wanted to suggest a new relativistic enmity model. All the suggestions I've heard for fixing current enmity issues revolve around increasing the cap or lowering enmity gain per action. This, however, makes reaching the cap impossible, because the higher you get, the harder it is to accumulate more enmity. Eventually, if you consider a constant VE decrease, each player would settle at a certain balanced VE level, depending on their enmity output, be it from dealing damage, curing or using other kinds of hate tools.
I would really appreciate if someone would take the time to look over the math, since I rushed most of it, but it seems to check out. I would appreciate even more if someone at SE would actually look at it and play around with it, and possibly comment on if the need for a new system is at least acknowledged. This is just a suggestion of mine, I've made the page to play around with it myself mostly, but if someone has a different idea (that doesn't revolve around the previously mentioned cap increase) feel free to mention it.
Details to everything are on the site.
