Opinion: will you be reluctant or eager to switch from 5E to 6E?

Honestly, I dislike LR classes. From a purely 'game mechanic' stance, 'Nova-ing' is a logical strategy (even it makes you a kind of crappy player). If the DM then punishes players for Nova-ing by denying rests, they are kind of being a crappy DM. The whole dynamic basically encourages crappy play or quite severe curtailing of player agency (i.e. static adventuring days).

I disagree. I think managing resources around the uncertainty of replenishment is an important part of the problem solving process, to say nothing of game balance. If a wizard can just burn all their spell slots without concern that they might not have a resource they need, then the limits on the resource are not actually affecting the game at all and may as well not be present.

If youre going to nova, or burn a dozen spells unlocking chests, or hunting for traps or whatever, you should have to weigh the opportunity cost of those resources not being available later when you decide to do those things.
