T12 Swap canceling Arcane Power on pull

[stabber7777]

When I use the tier switch, my arcane power is instantly canceled and put on cooldown. This destroys my damage, and is really confusing. I've tried searching it, and had no success. It only seems to happen for my mythic gore switch, and my main switch set works fine. I've tried remaking the set, and it hasn't worked as well.

Are you also switching trinkets?

What macro are you using?

Are you also switching trinkets?

That's my guess as well - could even be something simple like swapping trinket slots between the 2 sets.

Apparently I am, didn't know that it canceled your arcane power, thanks for the help!
