On a personal note, the only reason I... participated was to check off an item on my bucket list - can you get a WP for a ball of rubbish? The answer, is yes!
With regards to there being a range of easy to insanely difficult, I'd say that is fair enough but is of course subjective. I'd ask whether Mur said this exact example was appropriate, particularly if this is going to be a hill to die on - but I don't care plus I have said the forbidden words now!
All in all was good fun though, I enjoyed the quest.
