I, for one, really like position based advantage/disadvantage for many reasons:
1. It adds quite a bit of tactical play.
2. In most cases martial melee considerably outperform martial ranged in 5e and IMO it's ok for ranged to get a nudge there.
3. It just makes sense, really.
IMO it's a nice touch.
Not arguing. It’s your opinion and I’m okay with that. But what would you suggest to solve the problems I’ve mentioned above that steers away from the raw comparison of melee vs ranged?
