I’d really be fine with or without random encounters. I don’t think they really prevent people from spamming long rest because they can’t be so difficult that you are unable to beat them with few/no spell slots. Personally, I just really enjoy combat in the game so it would be fun to have more battles and more variety of enemies. Also a chance to try out different abilities you might not normally use since you’re about to long rest anyway (that’s what I end up doing in Solasta).
