Uncanny that the same person who was pushing the point that players can get what they want via mods was also trying to majorly argue to make the game be a certain way.
If you're so ok with players needing mods to have the things be they way they want, then let them have the game changed to be their way and YOU can mod it to be your way.

Kinda amazed I got through 9 pages of this with nobody mentioning the Battlemaster's counterattack, which uses one of their limited dice. Same as using a spell slot for a reaction spell, of course, but still.
Definitely need the ability to decide whether or not to use reactions at the time they'd be used, not beforehand.
