See, I don't use haste potions. I avoid scrolls whenever possible. I don't touch most consumeables. I ignore bombs and I don't even throw healing potions.
I feel all these little things make classes less special and ruin the strategic aspect of combat. This is why I would hate a lot of playthroughs and a lot of people would hate mine.
With scrolls, arguably you don't need caster classes at all. Ever. With healing potions (and haste), you'll never need healing spells, as the right configuration can throw 6x of them per turn. Explosives can kill anything, alive or not, before combat even starts. The enemy will be very happy to watch barrels slowly appear out of thin air.
I've experimented with all of those things. I decided I like none of them. Therefore they're banned in my playthroughs, and spells slots actually matter. Long resting too little will never be an issue (if you keep casters around). Spending all your spells slots too early in the day is still a bad idea, at least if you try to get the most out of 2 short rests. Which I will. Again, personal preference. I despise excessive backtracking, so I will just not.
I also don't play warlocks. No matter how I play them, I feel like another class can do it better, or they're multiclassed to the point that the warlock levels are really only flavour. This is probably how you feel about rogues. I don't think we'll ever agree, so it is what it is.
No, I like rogues just fine. I just think they are easily replaced in the party, because the mechanics they are supposed to be good at (stealth, lockpicking, trap disarming) don't pose any challenge. Lockpicking is easy due to overabundance of tools, last I've tried stealth Laezel in heavy armor could do it, and I never found any traps as dangerous in BG2. And I think your post kind of showcases that, that you need limitations to even make certain roles feel more useful.
Which is why I wrote in the beginning that no role is necessary.
