They could do that, but then I guess it wouldn't be 5E rules at that point.
True ...
But looking at chromatic orb im not honestly quite sure if they care.
The best solution would be to limit encounters and quest rewards to the expected level gain desired.
But that would create another problem ...
Either you would need players to do everything ... in order to get level you want them to have ... or there would be too huge gasp between copletionist and casual. :-/
Since people around here allready said that they managed to reach level 8(!!!) just durin Early Acess that dont give us even whole Act 1 ...
You can easily end up in simmilar situation as Dragon Age: Inquisition had ... where last two locations was litteraly wasted bcs you allready had the lvl cap. :-/
