While messing with Resource Cost Reduction (I managed to get my Shield bash cost 4 =D) I noticed that if you equip the Akkhan set, use Akarats champion, then unequip the peices you keep the 50% RCR from the set bonus for the duration of Akarats.
So in short:
1) Equip Akkhan 4 set
2) Use Akarats champion
3) Swap back to whatever gear you were using
4) Enjoy 50% RCR for the duration of your Akarats
This makes Rolands set insane, as you basically dont have to worry about Wrath for the duration of Akarats
This also works with the 50% CDR on Akarats which makes sense, but the fact that you keep the 50% RCR even after unequipping the peices is the part I think is a bug
