Efflorescence to help out with pet/group heal but that talent can be placed anywhere else, one point in Nature's Ward should suffice. Regrowth seems to now take the role of Nourish as the fast heal. Nourish with 2 sec cast will be easily interrupted and taking talents that improve it is a bit questionable. (atleast will be at lvl 85 when you can also get some hots improvement from balance)
Taking Empowered Touch. Assume your target is low on health: You cast Swiftmend, Regrowth then Nourish.
If you get interrupted or CC-ed on Nourish then lifebloom will most likely have the time to bloom.
If you don't get interrupted you get free upkeep of lifebloom because of Empowered touch.
So you keep lifebloom up with nourish and you chillax when you get cc-ed cus you know lifebloom gonna bloom and get friendly back up on hp.
Take Entangling Roots as one of the major glyphs. Rejuv, Swiftmend and lifebloom as prime.
