To master a spec

[Drasco]

Looking for advice.

I have been playing with boomkin as a main since Bfa S4 and only focusing m+. I want to master a spec but I am far from that as an avarage player (doing +16 and +17 keys).
I see many players switching to meta in each season that performing well but I want to stick to one spec/class but having a problem to decide which one.

I am thinking about the following:

1) Balance druid:
I like the spec, many utilities and always welcome in groups but you need to think always ahead. I think it has a high skill floor.

2) Hunter:
I am enjoying to play BM and MM. The good thing is about the two specs that there are more chances to get a good performing spec.
Obvously hard to master a class or spec but I feel these two are easier.

3) Shaman:
I used to play enchancement but I play elemental now, both specs are fun to play. Elemental has a straightforward build which makes it easier but obviously it is not enough to master it.

I want to choose only one from these three options. I am getting closer to the hunter but I don't raid so no chance to get the lega bow, which makes my life harder in S2.

As I am kinda a new player and I don't have much experience about these classes in previous expansions.
What would be a decent choice?
Thanks
