Should Channeling a Skill Count as Using It?

The Trickster's Weave the Arcane notable passive has the following effect:

"20% increased Attack and Cast Speed if you've used a movement skill recently."

When I use a channeled movement skill such as Charged Dash, I notice that it does not trigger this effect from Weave the Arcane while channeling it, but only when the channel is ended and the dash is performed.

There are circumstances where I am content to channel the skill from a fixed position for an extended period of time (maybe I'm safe behind cover and I send my charge ghost into a room full of enemies). I could sit there all day channeling and never trigger the speed bonus from Weave the Arcane.

There's no evidence that this is working other than intended, but it does feel bad that I can channel a skill for thirty seconds and never be considered as "using" it.

I'd be interested to hear thoughts and other cases where this may/may not make sense.

The Slayer notable +5% increased Area of Effect max 50% has a wording or synergy problem as well. It doesn't work for Warcries however the gem "Increased Area Effect" does work.

There's no wording difference between the two and given the node was totally broken for a month when re-worked I question what it actually works with intended or otherwise.
