Yeah probably. Honestly I don't know how popular MP10 carrying is these days for rings. The value of the Hellfire Ring took a nosedive when they bumped up the XP rates per MP level. It used to be that 35% XP was a big chunk of bonus XP when you were only getting +75% or whatever from MP bonus. But now that at MP5, which is pretty easy to do, you can get 158% bonus XP that +35% is less and less of a bonus by percentage of the overall bonus XP. I don't really know how many people still run around with Hellfire rings equipped. I know I ditched mine in favor of a ring to give me actual DPS stats. Considering at MP8 you get +208% XP, +100% XP from NV5, +27% from Ruby Helm moving from +335% to +370% is only a 9.5% increase.
