After playing 2024 for a couple months I am thinking about giving full casters each one weapon mastery. There are two reasons for this.
I wouldn't even if I played 2024. Casters already have enough going for them, they don't need to take the martials shiny new toy.
First Truestrike is the most common Cantrip I am seeing cast in combat now, but it is not doing the cool effects that martials are doing with attacking (or using Truestrike).
Good, it wasn't meant to. It was meant to allow casters to make weapon attacks without having to rely on lower STR or DEX scores to do so.
Second the Gish classes seem really gimped and a little less dynamic in melee. Valor Bards are super powerful and lots of Clerics and Bladelocks are pretty effective in melee too, but something is missing compared to the martials. Something is missing for Monks too. The end result is the casters end up taking a Paladin or Ranger level anyway for the mastery, without losing a spell slot.
Gish "classes" are Paladins and Rangers, who already get weapon mastery IIRC.
Gish "subclasses" are not as dedicated to weapons as martials and so do not have weapon mastery by default. As you already say, these options are "super powerful" and "pretty effective in melee" without weapon mastery, so you want to make them even more OP?
Monks in 2024 are crazy OP as everyone knows.
If I kept it to one single mastery the martials would still have more weapons, so I don't feel like it would step on their toes much.
It would incredibly step on their toes. Most PC use one or two weapons AT MOST, and a spellcaster using a weapon will most likely ONLY use THAT weapon because that is what they use...
Overall, it is unnecessary, unbalancing, and unfair to non-casters. If casters want weapon mastery there are other ways they can get them and sacrificing something for that benefit makes more sense IMO than just gifting yet another martial toy to casters.
However, I think this thread isn't about really asking for other peoples' opinions so much as hoping to see support for something you want to do anyway? Given that, as long as you and your group are happy with it and no one feels their non-caster is cheated by it, just try it and have fun playing your own way.
