at the moment i am running as follow: 1. Bio Capacitor 2. Bio electric surge 3. Ionic Drain (less useful, but still testing on its usefulness) 4. Electrogenesis (heal over time) 5. Invigorate (supercharge and i must admit one of the best supercharge as a healer) 6. Galvanize
the stats I am running is % chance crit heal and % crit heal amount. doing quite well in t1 alert when there is a proper troller not one who doesn't give buff or power.
problem with electricity healer is, i can heal loads. however, because of the lack of shielding ability, i find that i have to play with smart players who don't get one shot by bosses :S
i need to double check on my resto, but its probably not that high since i left that stats mainly to gear.
thing about electricity healing is that you heal so many times, so i thought its best to boost crits. Galvanize's heal is an amount times however many allies are in your radius, so more chances to crit. same goes with ionic drain and bio capacitor.
however, would it be better to get resto instead of crits?
despite with nothing which can give me resto stats (before i get my first piece of t1), i've got called a good healer in arkham :)
