Suggestions new Multibox team?

So i am planning on making 5 US accounts

Now i am wondering, what would be a nice 5x team to do Mythic+ with once i've leveled them to 110?

I know 5x Hunter are excellent but that's nothing new.

Any suggestions besides Paladin, Hunters?

Long, recent thread on that topic over at dual-boxing.com.

Not recent enough, sadly. Nothing about 7.2.5 in there.

Despite a few nerfs Guardian druids seem to still be quite solid. And the few boomkin I know that play solo seem to do quite well on the DPS meters. I think 5x druid is always going to be strong.

I play 3 affliction warlocks and im loving it. However when it comes to world pvp, a simple fury warrior can annihilate me easily by popping all his CDs.
