Tips for keybinds for vengeance?

Basically I use the same key layout for all classes. I have 2x12 buttons where I can bind skills to and this works for havoc (taunt is off because of azerite essence).

I want to give vengeance a try, the skills are refreshing while still playing demon hunter. The problem I have is that I don’t seem to have enough keybinds left to put the skills on. I’ve managed to fit all skills on my bars, minus 2 sigils and taunt (well, I do need to bind that!). Are there skills that I shouldn’t be using while tanking, that I could remove? I’m currently not really aware of the correct talent build, so I’m following the icy veins guides:

  • Abyssal Strike
  • Fallout
  • Flame Crash
  • Fracture
  • Spirit Bomb
  • Last Resort

So basically I’m lacking space for skills, what to do? Currently this (and lack of gear for tank spec) is withholding me from even really trying it.
