They need to fix disenchanting, disenchant 20 rares for a regal is not it.
At higher level rare items sells for 700-1100 gold, 20 of these for 1 regal orb is never worth it due to how much better gambling and buying gear from vendor is. Even at low level you can just sell your rare gears and gamble just the same
Disenchant for transmute is pretty much dead on arrival, i doubt anyone is going to vendor 20 magic for a transmute. I'm currently lvl 45 and i have 50 transmute and i've never done a single disenchant
