I've updated your score. I will continue to update scores until I'm done testing the new formula and have the new thread setup.
The reason that the ruby is better for you is that you get full credit for the XP bonuses whereas your EHP was already so high that adding 18% extra hit the diminishing returns wall of my formula so you only got partial credit for it. The new formula will help somewhat, but heavy tankers like you will probably still be better off with the ruby in helm.
I wish there was an easy way to make rubies in helms equivalent to amethysts so that we don't get this discrepancy, but there isn't. OTOH, the extra EHP you gain from amethyst is of marginal use to you but is of huge importance to someone with 600K EHP, so it makes sense that the low EHP dude gets more value from the amethyst in the formula.
Thanks Celanian, I appreciate it. It is kind of cool seeing how the different pieces effect my scores in the various rankings (here, PVP, Heroscore, ect.)
I personally feel like this score should reflect when you are most godly. I.E. I am going to wear a purple gem in my helm during MP10 Uber bosses, as it does allow my character to be better overall, even though the 18% more HP may not benefit me as much as someone with much less HP/EHP. Perhaps you make the requirement of not allowing a ruby in the players helm to be counted, just for scoring initial scoring purposes only. Because I dont think anyone in this forum can argue that the purple gem makes every characters much stronger than a ruby does, the only reason to wear the ruby is to level faster, not necessarily be the most godly.
Now in all honesty, I do not farm with a purple gem in my helm and I use my hellfire ring, as I am trying to get to paragon 100, if that will ever happen! I use my SOJ and Purple gem for high level ubers and I use my Oculus ring for PVP Score lol (That ring is a EHP monster btw). But maybe we can move to the idea of not scoring for experiance gain all together in your forum and it can alleviate a lot of the guess work and provide the best numbers for who is infact most godly. Just floating some ideas around here, it may level things much better.
