You forgot the text of the sorcerer class feature in question: "Converting a Spell Slot to Sorcery Points. As a bonus action on your turn, you can expend one spell slot and gain a number ofsorcery points equal to the slot's level." Nothing there says you can't use non-sorcerer slots to fuel this feature.You forgot the spellcasting multiclassing rules.
Pact Magic. If you have both the Spellcasting class feature and the Pact Magic class feature from the warlock class, you can use the spell slots you gain from the Pact Magic feature to cast spells you know or have prepared from classes with the Spellcasting class feature, and you can use the spell slots you gain from the Spellcasting class feature to cast warlock spells you know.
It explicitly lets you use Pact Magic slots to cast non-Warlock spells, but nothing states you can use Pact Magic slots to fuel other non-Warlock class features.
Outside of Coffeelock, using Warlock slots to fuel non-Warlock class features doesn't cause a problem. With Coffeelock, it does.
So you read the rules strictly, and state "there is no rule stating that Warlock slots can be used to fuel non-Warlock class features", and the Coffeelock dies. All RAW.
Now, the common sense version of 5e multiclassing is "slots are slots are slots", but that isn't what the rules actually say.
No. There are two problems. One, they're obsessed with combat. Two, they're hard-core optimizers. Obsessed with combat I can generally handle. Optimizers who want to break the game, not so much.Note that this a problem of characters obsessed with combat, not optimization.
Yes, it is.But the optimization isn't the problem here.
And if they weren't obsessed with combat the problem of super-optimized characters would remain.If their PC where incompetent at combat and they still Leroy Jenkinsed every single situation, the problem remains basically the same.
As stated in the OP, I've run through the possibilities.The option of "don't play with them" was presented.
The option of "use mechanical levers to fix optimization issue" was presented.
The option of "modify the game so they have fun as well" was presented.
Every option was shot down as something you don't want to do.
Mechanical levers will utterly destroy the non-optimizers in combat. That's bad.
Modifying the game so the optimizers have fun will directly cause the destruction of the fun of the non-optimizers. Modifying the game so the non-optimizers have fun will directly cause the destruction of the fun of the optimizers. When my goal is for us all to have fun...
You left out the real problem that they're optimizers.What more, you are using "optimizer" to include "a player who refuses to do anything but combat and is disruptive at the table when things don't go their way".
You appear to have 4 problems.
1. 2 players uninteresting in anything except combat.
No, they optimized their PCs to the point where combat trivial.2. Those players are disruptive when they don't get the combat they want.
3. Those players optimize their PCs to be good at combat.
Right. Which is why I'm here trying to get advice or at least some commiseration.4. You don't feel any responsibility to do anything about any of the above.
