Hey, posting another one here..
This also works with lucky hit while barriered but I think Blizzard may have added that to the base rolls for every class now.
Anyways onward to the exploit..
If you get a pair of non-class specific gloves on your barbarian or druid or whatever non-rogue that have an open slot and no class named in the bottom right corner of the item you can trade them to an alt rogue on your account and reroll the open mod to get "Attack Speed Increased after Dodging an Attack" which is normally locked to rogue only.
I believe this also works with rogue-only "Dodge chance against close enemies". IAS after dodge is incredible on Double Swing barbarians in PVP and PVE alike, likewise for Crone staff druids.
You can also do this in reverse-- get a glove that has dodge ias + ias + crit from a rogue that is classless and then put them on your barbarian and roll your +3 skill.
