Spec, Dual spec. How often do you play other specs? MM, never. No spec is competitive with MM
So what happens if BM becomes the best spec in legion? Or surv? What happens if we ask you to play BM on a fight like Xhul? Even if MM is the top spec currently, you should be able to swap to your other spec and play them close to, if not as well as the top spec.
For the guild thing: People get shit on in this raid. Most of the time it's fun stuff, sometimes it's business. You need to be able to take a beating in teasing and criticism alike. I'm not sure if you know the difference between that and flat out bashing.
You should be upgrading and putting in the best things into your gear no matter if you're in farm or progression. Take care of your gear and farm will be smoother and quicker.
And why do you want to play your hunter that is behind in legendary ring and gear, and not your main? Do you reroll often? Are you sure you'll keep enjoying the class in legion? What if hunters are not as powerful as they are now?
Wondering why you only have 1 arch kill on main and no re-kills since dec.
