[2022] BB Gameplay, what percentage is luck vs skill?

It's funny that you mention this because this is essentially how BBs were described to me when I first picked one up. They're slow, sustainable and can either pack a huge punch or whiff massively based off precision, dispersion, angle and some good old-fashioned RNG.
For me, I am particularly enjoying them based primarily off the rush of landing those massive citadels. Every time I land one I seem to forget the 100 pens, overpens or straight up misses that happened before.
