In first, i think of it too, but they didn't buff it, they buff Vivify. So, if i can do more healing in 7.2 using only vivify, it will be the case in 7.2.5. The only case where EF is better maybe on a boss with "little dmg" on everyone like Nythendra. We will see on live, that speculation.
Don't play too mutch with the 7.2.5, we want to use it too
I agree ! Spamming Essence Font is way to weak on Krosus for exemple. Monk should do healing like a burst, not using some kinds of hots like Druid. But i understand, Essence Font is easier to use... No need to think on who, just think on having the raid around us.
Expensive in mana ?
I will try on my next raid Effuse + Sheilun, i never thinks of it !
