Right now it's hard to skip the night with the 80% sleep requirement. I propose only 50% of players being required to skip the night. 60% may have worked fine last season, but I think more will appreciate a lower percentage than otherwise. It's not like its a huge deal anyways, so it shouldn't be a problem to at least try it. 

I'll add to this, that the community on wildercraft is great. I'm almost certain if people want the night people will respect a chat message asking not to skip.
A lot of the times when caving or being underground, it's difficult to really keep track of time - and since the x/y players are sleeping message is so frequent (when people aren't wanting to skip) it isn't as obvious - even with people typing in the chat - when you're focussed on something else. Lowering the % will make for a better played experience imo.
