One ability for single target?

I’m level 71 and it seems like DH’s entire single target arsenal is… one ability, being chaos strike? This surely can’t be right? I love pulling groups of mobs and using the different aoe abilities but singletarget is 1-1-1-1-1-1-1-1-1. (except for the charges with cooldown) Do you guys find this fun? Aldrachi Reaver makes you incorporate your ranged singletarget ability but there’s really not much more to the single target abilities we have?

You have felbalde, vengeful retreat, blade dance, eye beam, essence break, immolation aura, throw glaive/reaver’s glaive, sigil of flame and sigil of spite as well.

You should use blade dance on cooldown.

As others have said, you should be using even what you consider AoE abilities on single target.
