Safe Fractal Builds

Hey!

I've just jumped into fractals recently as I've neglected it forever!

I'm a little stumped on a safe class to pick though now I've reached the point the game is recommending agony resistance at fractal level 20 and I have to really double down on gear and infusions.

I enjoyed the power virtuoso on discretize but was finding it a little squishy in some scenarios.

I also mixed in some alac druid from a meta battle build which actually looks just to be the raid build. But I felt immortal with this pumping out tons of heals but see this not being a very popular Fractal build which is a shame as I really enjoy it. I tried chrono as that seems the go to healer but was quickly overwhelmed trying the rotation ok the golem.

Any recommendations for a safe build with a relatively straightforward rotation?

Thanks!
