im wanting to play an offspec, wondering which one of the two are in a better position and do well in their roll.
i tried BRM in an instance once and LITERALLY had no fuckign clue what i was doing.. my custom ui though didn't show the 'stagger' stuff, so thats probably why it was so confusing.
Mistweaver is by far in better position at "healers list" than BrM at "tanks list". Both have to work harder than other class (Rshaman or Rdrood and Prot Warr for example) but MW have better results.
Depends on your surroundings. Are you in a fixed raid group? then ask the raidlead what you need. Do you want to Pve or PvP?
Remember that with DH, a new tankspecc that needs almost no skill for dungeons is around.
At the end of the day, test both for a couple of days and play what is more fun, the contend will come by then.
And no matter what is more in demand (tank or heal) both are needed more than dps (im most cases at least)
Personally I think its hard to tell til the raids come out and you can get a feel for the class in a harder setting, If you're just looking to do dungeons with the offspec honestly either are fine, i can heal just about any tank on mw and can tank mythic dungeons easy for the most part with no healer. In reality do what Narzok said, try them both a bit and decide from there.
It does not seem too hard to keep both offspecs to a reasonable level. both offspecs off mine have gotten to their first golden trait and are both got alright relic slots. Gears all 'the same' apart from trinkets. (ofc stat prio is differnet for MW but just get mastry for the other two - I think)
MW is really strong and can put out some insane healing, the trick with MW is mana management.
I have been healing mythic dungeons since Ilvl 825 and not once had a real issue.
The MW kit has so many ways to deal with things it is really a fun class and talents provide completely different playstyles to keep things fresh. And whats not to love about the crack bird talent (Chi Ji)
For BrM I have tanked all the heroics and honestly it was very easy, I am sure the mythics will be fine as well I just have not tried to tank them as I am enjoying MW tooooo much.
All three my weapons I have taken 13 traits in, up to the point where the next trait is like 8000AP. From that point I have been focusing on MW weapon.
For brewmaser make sure in your 13points to take obstinate determination, that ability is insane.
