I had a look at your current talents, and I’m not going to tell you how to play, but these aren’t all the best for dungeons (if that is what you play with that).
Not saying mine is the best setup, but it works for me, and I keep people alive with that.
Also 9% haste, is kind of low, you will be slow. I personally pick flash flood, and I’m no longer mr slow caster.
You pick both Deep Rooted+Ascendance ? Primal Core? If this is what you play in M+, then I’m sure you will have issues.
Also no focused insight, no master of the elements, you miss a HUGE buff on your ST heals, and even on chain heal.
I was on the same page as yourself, I even started out copying the wowhead talents. It didn’t work for me, I spend a week tweaking my talents, my current setup is for my playstyle close to perfect (still need to test high tide)., the only small changes are with certain affixes, like frost shock for explosive week, and earthgrab totem for the one with the adds coming at you after killing an enemy.
Also the buffs from 10.0.5, no matter how little, are very good for ST heals.
Also saw, no lava surge. Playing with Flame Shock and Lava Burst + procs, Master of the Elements + Focused Insight, that should improve things. Also check the dungeon loot, try to go for places that drops haste/vers gear, aim for 20% haste. You can even at the point (when you check my talents), drop flash flood and take torrents (that’s my plan at least), once you reach like 20% haste, I’d go for crit next and try as little mastery as possible.
