I recently went from a 219 piece from 5 HToC which were plate dps legplates to Tier 9 legplates for 50 Emblems. I had a score of 2508 with the 219 piece, which was fully enhanced and fully gemmed, to this new piece which had an extra epic gem slot and it also had the same item enhancement. My score dropped down to I believe 2484. The new piece is lvl 232 and is T9 gear. why would it decrease? All other upgrades have always increased my score except this one.
