Just got a heroic neck from xavius and want to replace my 850 version of the same neck. The thing is that I'm also losing out on a socket when I switch pieces. I lose about .30% crit but gain a tad bit of haste + Stam + ilvl. Do ilvls on pieces that don't give str matter anymore? Or should I just run the 850 neck until I get a socketed upgrade.
