when we ask 'what and how can we obtain light/dark element bookmark?' back before cuze it is shown in game there but to nowhere to obtain it. When it does, this is what SG thrown at us, being absolute stingy and such ridiculous way to obtain it plus, we only get 'chance' to get these bookmark once every advent event and by 'chance' is everyone get to have garbage 3* all the time. Long time we demand moonlight to have pity and we still have not get it done yet. 3 years and lots of moonlight hero being added, at point there must be pity added or else it is just SG being terrible.
