When you get past lvl 54 then there is not much point in doing other adventures than fairytales, as the old adventures gives so little XP compared to what you need to level up.
But as it is you only get Valiant little tailor and Ali Baba the young woodcutter from searches, and have to get the rest of the adventures from loot. What this means is that you end up having lots of valiant and woodcutter, and not so many of the others.
It does quickly get boring to repeat those two adventures so many times, can BB please increase the drop rate of the other fairytales so we can have a little more variation?
