EDIT : I got the same usual response that if most players give the same opinion they will "consider it"... So let's try
there are just too many different hero soulstones in the shops... I know it has been discussed already in the past, but with the new additions in the latest update it's even more crazy. I don't see a reason why we are forced to waste our hardly-earnt shop coins just to have a chance to buy the soulstones we want/need.
so please replace the soulstones by hero soulstone chests that would allow us to choose the hero soulstones we want.
very easy to implement...
PS : on another subject, please fix the pet ability upgrade bug!
