I did research for awhile and found some posts. Most of them were asking the same thing. I've seen a few equations for specific things but not a full list. It just seems so silly that this doesn't exist in the public domain. It's critical information to hardcore players...
Lol..Everything in every game is all math. (Check for the episode of Numbers where "Charlie" explains how a RNG works.) I worked out the "secret" formula for Lotro stats. I had spreadsheets to figure out what each piece of armor did to each stat, base and auxiliary. I just plugged in the numbers to see what my health/magic pools would be. Just dont really feel like taking the effort in this game yet.
