U can always just use protect -> swiftcast stoneskin 2 at the start as ppl usually take a few sec to load etc.
During start of pulls pop sprint cuz u know, heals don't require tp. Once the tank stops moving it means it's time to fight=
- hardcast medica 2 with regen on tank right after with divine seal on
-turn on CS and use swift cast stoneskin on tank
-turn on PoM with shroud activated and then proceed to holy spam till u drop to like 10% mp imo
* go out of cs if tank drops faster than ur mp lol
Also learning how to heal tht much damage with only like 400ish mp at the end is a prob something u might want to practice cuz cure 1 procs with a free cure 2 can make the pull or break it lol
If something is after u, u'll probably have to tank it cuz tank might be too busy trying to not die / might not notice you.
