Sharpshooter vs GWM

[MaxWilson]

Disavantage with glaive/halberd/etc against prone doesn't make any sense really.

Regarding AoO nonsense, being paralyzed means every attack against you has advantage and is an auto crit, so I take it like you have no guard at all, why doesn't this generate an AoO idk.

I wonder if there's any reason not to implement a houserule like this:

Condition: Unguarded
Anyone in melee range may make an opportunity attack against you with their reaction.

Retreating from melee at more than 1/3 normal speed without Disengaging makes you Unguarded, and being incapacitated also makes you Unguarded. (Stunned/Petrified/Unconscious all make you Incapacitated and therefore Unguarded too.)

It does make mobs of melee monsters stronger, and it makes Hypnotic Pattern an attack spell (can use it to trigger opportunity attacks instead of to disable), but would any of that be bad for the game?

For grognard DMs, add the following: A spellcaster is Unguarded while casting a spell. Has the nice side effect giving you a reason to have actual fighters in your party instead of just Cleric 1/Wizard Xs in heavy armor with Booming Blade/Greenflame Blade for good melee damage and full spellcasting.

Worth playtesting maybe. Thoughts?

P.S. Beholders, Black Puddings, and other 360-vision creatures can have their own special trait, 360-degree vision: retreating from melee never leaves this creature Unguarded.
