What you were expecting to happen, and what actually happened
The first skill of common rarity troops is for all of them 10 minor trait stones and 4 major trait stones with exception of the guardians, but there are 4 troops which cost significantly more for no obvious reason.
The first skill for all rare rarity troops is higher than common rarity troops, but it is always the same and I checked that for ultra-rare as well… Probably the same is true for second and third skills… There is a consistent pattern, but these 4 troops do not follow that pattern, so I suspect it is a bug in the game balance. I am not sure if I remember the names correctly:Trodoglyde, Penguin, Aurai and a bat with a name I don’t recall… Looks a bit like a Golbal from Pokemon.
How often does this happen? When did it begin happening?
How to reproduce:
Just try upgrade of these troops and go to skills… And compare with other common rarity troops.
