Why Was the Ignore Button Removed From Chance Cards?

With the chance cards there is one option that will be right more often, so option one could be correct 80% of the time and wrong 20% of the time while option 2 could be right 20% of the time and wrong 80%. I suppose that's to stop it getting boring as you would otherwise eventually learn which one to select and there wouldn't be any risk. But yes they could add an ignore option for those that don't want to take a chance.
