“It’s probably Matt Mercer’s fault.”
I was with you until there. I think everything up until number 7 is fine, but 7 goes a bit too far.
I dunno. It can make the tactical situation more interesting. There is, of course, a huge incentive for melee to bum rush archers, so there's likewise a huge incentive to make sure they'll draw AoO's from your melee if they try it.
Also, it would (presumably) be symmetric: you get advantage when you bum rush their archers. Which provides an additional incentive for rogues to pull their short swords out.
It makes committed archer builds (Fighter/Ranger, and SS feat) less attractive, but for those who haven't invested resources in archery and can freely swap between ranged and melee it shifts decision-making toward melee.
