Yeah just switch the ele from SF to ER

.
Nah, you don't need that much defense.
Just replacing the two monk skills on the MM to Prot Spirit and Aegis would be enough - but energy will be tight with Bone Fiends; better to take Minions and Death Nova over Putrid.
If I was to use an Ele for damage, I'd be more tempted by Dual Attunements on stuff like Rodgort's, rather than DoT stuff or Searing Flames (heroes aren't great with SF). Maybe even an Invoke Lightning build. Whilst doing that, you can slot stuff like Healing Breeze, Prot Spirit, Aegis or some cleaning on them if you want to (obviously only one or two of those four).
