Now this is the part where it gets really tricky, there are a lot of different speccs u can go as a resto shaman, depending on your setup, depending on wheter u like to use LHW, HW or even Chainheal, ive seen top tier players usin the most different speccs within the same mmr in, so our main Rule should be:
Whatever works for you, works.
But nontheless there are a several must have skills in the Shaman Healtree. BUT as a Shaman you are very adaptable to every encounter, Windshear, Grounding Totem, Around the corner in Ghostwolf against Casters. U can kite several melees with Ghostwolf, Frostshock, Slow totem, Hex.
Adaptable Playstyle - Adaptable Healspeccs
So as u can see there are many ways how a heal shaman could Roll. Even I am not sure if my specc is currently the best for my playstyle, but there are several Questions u could ask yourself, and with a little bit of WoW Gaming Sense and alot of PLAYTIME, you should be able to find your "Best" Shaman Specc.
The Questions:
- Is Mana an Issue?
- HELL NO -> more crit, more purge!
- HELL YES -> less crit gear,more mp5, try HW with Shield Orb Proc, effetive purges, Watershield up?
- Am i playing a Comp with alot of defensive skills i.e. Warrior, Deathknight, etc
- maybe u can go for a HW build . i.e. Meleecleave
- Am i getting hardbursted by alot of comps?
- Defskills i.e. Absorb Totem, Natures Guardian, alot of around the corner -> LHW more CRIT!
- Does my spec fit my playstyle?
- i.e. your using a HW specc with a LHW heavy playstyle
I will ad more Questions over time that should do for now, feel free to post a comment below.
