Return of Reckoning

Wanting to try something different with my Mara and want to know if there is a viable Monstrosity Spec that works with soloing. Wanting to see how the healing/armor pierce resist in Monstrosity works maybe going more defensive.
I know leaving out CC is a big no no, but just want to try to change it ...

I just downloaded the Amethyst addon but when the bar appears it does not show text. The first cast or 2 will show the icon spell name text and seconds countdown after that, those disappear and it is just the graphic bar filling up without text. Any fix for this?

Thanks in advance.
