I took resil: wisdom on my barb

[Amnestic]

To be honest, I've always felt that advantage from flanking is perhaps a little too much, given how (too) easy it makes getting advantage, and I've been wondering how to change it.

Maybe applying proficiency twice on attack rolls instead, effectively having expertise on said attacks? Or something else, like a flat +2 bonus to Hit, like in 3rd edition.

Flat +2 makes the most sense to me. Basically equivalent to Bless.

Could do it at 1/2 PB instead, so it starts at +1 and scales to +3. Direct 'expertise' feels like too much, though I guess that's how it starts at for tier 1 if you just had +2...
