Is it viable to just use weapon pool skills? And how does Cadence interact with ADCTH and conversion

I’m kinda new so sorry if this is a dumb question.

Currently theory crafting a tanky Death Knight at the moment to play as a tank with a group of friends, and not sure if it’s worth putting points into Cadence or not. I have a lot of weapon pool skills to choose from but I’m not sure if it’s viable to only use those and not actual weapon attack modifiers.

I know Cadence isn’t a typical weapon attack modifier (overrides weapon pool skills), so I’m wondering if the third hit works properly with damage conversion and attack damage converted to health.

Weapon attack modifier and WPS works together. (when WPS procs, it’ll amp. your attack more). I read a thread before, but don’t remember where it is.

Cadence is good if you have high attack speed and relatively high OA. It is strongest when you crit and reach 3rd hit fast.

ACDtH works along with %weapon dmg. So that means at cadence 3rd strike you’ll gain much more health than usual.
