Said this in other threads and I'll say it again: random encounters are a waste of players time.
If they are truly random here are a few issues:
* The player can reload a save before going to camp and roll again to not get encounter/get better random encounter.
* The encounter can wipe the party if it is low, and the party will steamroll them if they are full on resources. So this actually encourages to rest more often and with more resources.
* If these encounters give xp then they can be farmable and completely break progression. If they do not give XP then they are unrewarding
* They are unlikely to add any story elements.
Sure, adjusting the randomness could be a thing - for example as a DM I don't throw a random encounter at a party that is low on resources. But then again, I do refrain from throwing random encounters anyway as they don't really further the plot of my campaigns.
