enchants we can use are changing again, it appears most BC enchants other than some scope and wpn enchants will be the best for brackets 70 and lower
But he is asking about the changes that mean there are less slots to enchant at endgame
Well for one you could use TI's poll system.
Secondly the enchant changes mean nothing to twinks. Simply they are changing all current enchants to not be applicable to items over 600 ilvl, which will be pretty much all WoD gear.
And gems don't affect this bracket.
Your miss understanding the changes..
There not making its so ILvL 600+ cant use as much encahnts, there taking out most enchants in general, making it so (A guess) 3-4 items can be enchanted
(That's what I read of a Blizz Tweet)
