I want to make a tank for a variety of content that includes:
1. Mythic island expedition soloing (I will queue with my 2 alts that will stay idle in the boat)
2. Mythic+ carrying
3. torghast carrying
4. legacy content farming such as legion bosses or mythic bfa dungeons or even bfa raids
5. easy outdoor farming so that I won't have to swap specs all the time
6. Arena viability (not that important for me)
As you can see my main objective is to make gold with it. I was thinking druid because it's very flexible but still not sure what to roll.
Also, if there is another class spec dps or healer that has massive aoe that it's too good to pass feel free to mention it. Island expeditions solos are the most important for me right now.
