“It’s probably Matt Mercer’s fault.”
Oh I see, so you're saying since higher CR enemies are more dangerous, that spellcasters reaching higher level shouldn't make them any stronger than their foes.
No, I wasn’t saying that, although it might seem like an implication of what I was saying, which is just that a simple, clean, elegant way to build risk mechanics into D&D spellcasting would be to make risk proportionate to slot used.
A corollary is that the casters ability handle risk should also go up, so that as you level the risk of using low level spells decreases.
