I’m just getting to the endgame of BFA after starting up again a week ago. As an altoholic, I have nearly every class at 120 right now. I get way more time to play than my buddy, so I’d like to figure out a main that I could gear up with all of my time, and carry him through M+ runs on.
I’d just like to know what class (and what role) you think has the biggest impact in carrying M+ runs. Is it a beefy tank? Huge dps? Amazing healer? and which class is top tier for it?
Havok DH and Outlaw rogue for dps seem to make the biggest difference.
Brewmaster monk for tanking and resto druid for healing make runs easier.
I wouldn’t say any one class can carry, but the above 4 seem to make Mythic+ easier, especially if you stack them.
I’ve taken some guildies through low M+ as a blood tank. The damage output and survivability of tanks today pretty much ensures that even if 1 or 2 dps or a healer dies; there’s a good chance the tank can finish the job. Only a few fights have like true wipe mechanics or damage checks (TD’s last boss for example; if everyone else but the tank dies… there’s a good chance it’s over after 3 deadshots).
My vote goes for tanks as the best carrying role. I’ve only played a warrior and dk tank, and I personally like the dk tank more, though warrior tanks dish out absurd damage.
I run Vengeance DH, and assassination rogue. While I feel like my rogue does great at helping carry, it is must easier to carry on my tank. It is easier to get groups going, and you can kind of control what happens.
There are a lot of specs/classes that I like, but a few that I somewhat avoid. I don’t usually take priests, feral, warriors, or ret pallies.
An overgeared blood dk is going to be your best bet for an actual hard carry scenario
A case could be made for a very strong dps but carrying a tank is mostly a no go
I’m not saying blood dk is the strongest tank either, I’m just saying they are the ones with the tools to outmuscle ignored mechanics and to survive giant shots solo
It’s sounding like the general consensus is Blood DK. What about Paladin? It’d be nice to be able to carry him as a healer in case he wanted to try and tank, etc
Just go look at the recent MDI
Havoc DH.
Blade dance go wshsshshshshshs. 
Tank definitely is the best as if you have a bad tank the run is pretty much over. And a good tank can make everyone’s day. With corruption you can even do top dps as a tank.
So maybe prot warr / blood dk with TD
