I had some time this weekend to fraps the four bosses in the first instance in the beta, Temple of the Jade Serpent. At level 85, I’ve yet to have any mana problems, but will touch back on this subject when I hit 86. I haven’t reforged back any spirit, and I’m still sitting at about 2600. A few things to note: I had some trouble dropping mushrooms on the last boss, I would drop them, but the third shroom just would not drop. It was getting increasingly frustrating. Tree of Life, when utilizing the lifebloom glyph, is currently instantly adding 3 stacks of lifebloom to each target you cast the spell upon (you can see this on the third boss). And lastly, I found a particularly nasty bug on the last boss involving ToL and Mushrooms. If you pre-plant your shrooms and swap into ToL during the shadow phase of the encounter, and then try to detonate them, you will critical error out. I only caused us to wipe three times to this ;)
I’m a little clunky as my keybinds still aren’t second nature to me yet, but it should give you a relative feeling for how healing is looking so far.
Please don’t hesitate to let me know if you have any questions!
