I think that far too many YAVP mention that they "got precrowned with X".
How important is precrowning for winning?

Is it almost a must (i.e. more than 80% of games that managed to win had been rewarded with a very good precrowning item or two)?

If it is, would it make sense to make it much easier to precrown (as standing near an altar and sacrificing monsters is not exactly interesting)?
Or should it be nerfed, instead?
