Ret, DK or Fury for a solo player

[lexonio]

I'm willing to play a Plate class in BfA, but I mostly play solo and need something good for Random BGs, 2s and probably RBGs.
What works best out of these three? I know Ret is a self-healing monster, but lacks mobility. Is DKs self-healing as good as Rets? So I need something that will work for me as I don't have any BfA experience yet to judge.

Thanks in advance.

Retris self healing might be nerfed a bit though.
Cant remember Frost DK healing cd but UH got 1 that is a double edge sword.
Fury will still need a pocket healer, hes a warrior after all.

Regarding mobility it depends a bit, but generally Retri > Fury > DK.
You dont mention fun factor though, in that regard I would say Fury > DK > Retri.
Then there is utlity, probably most important for the 2s aspect and I cant tell you anything about that, just know at least UH dk is shit with utility after losing their pet stun and bringing no real buff either, 5% leech is useless.
