I've played with various FK builds strictly for PVP, both 61 and 51 point builds with secondary souls to improve SP/Healing/Survivability (Harb/Arb/SC/Chloro). I only have 1 piece of Slayer's gear (so no crystal bonus) and both the slayer's MH/OH (no wand, yet).
I'm noticing some FK's healing output nearly double mine, and after running a parser saw they were using Legendary ER. I switched over but now since LER is essentially on a 6-second CD (unless using Cold Snap) what do I use for filler? Legendary Bloom and Rime are only healing for 8k-ish or less and Bloom has an 8-second CD.
Let's say someone with one of my barriers is taking damage: If all my big CD's are down, I could drop Telluric Burst, Bloom, and LER, but now Bloom and LER are on "CD" ... so spam Rime? Considering it only heals for 8k and someone could get blasted by 22k + hits (ignore the 70k hits in this example!)... it just doesn't seem like the right solution.
