Personally I feel that everyone that enters should have a round in preparation regardless of whether they can host it or not.
I understand that RL (exams/family/winning the lottery/…etc) gets in the way of fun but surely we should be prepared?
I had a round planned, Granny Mover, but * censored because this comment may cause dissent and we don’t want to appear bitter…again * and so I ran it as an additional challenge. I have another one already planned on the off chance that I won. If someone ran a round very similar to mine [spoiler](then you’re a bit sad 
)[/spoiler] then I’d have a rethink so that I am prepared.
As I said, in the first word, this is my personal opinion.
