see I have the event stuff around level 30 and sloely push it up now and then when I get a chance, most of my rings are now 8+ with lots of 9+ any earrings I'm using are 9+
Bracelets and necklaces I have a couple of spare maxed ones lying around....
I like to keep around 2 mill on hand - so I tend to go on an upgrade runs when I go over 3 mill - that extra few hundred in stats is not vital enough to burn me out on
