DH or DK Tank for M+

Reinvigorated with the game after finding a new guild, and have realized why I always play a tank.

Planning on running m+ (15’s) primarily, looking for insight on which class to invest in gearing.

Currently debating a DH or DK. The ONLY reason I haven’t just chosen the DK outright is because everything I’m reading says that the nerfs ruined them, and that they’re incredibly squishy now.

Any input? Are DKs simply not worth the investment if they aren’t viable in the 15-20 key range?

Thanks in advance!
