Quick Nock (with its trait) actually covers a wider area than Wide Volley does, even though the name would have you think otherwise. Unless you absolutely have to AoE from as far away as possible, there's really no reason for Wide Volley to exist at present unless you just like burning through your TP faster for some reason.

Ast gets to keep Royal Road when they leave an area, but the rng of card draws isn't adjusted?
What exactly is there to adjust? Are you just saying you want Balance to have higher odds of showing up?

It's a 1 in 6 thing; you're not supposed to get the one card you want most of the time.
