Arcanic stones - unbearable and monotonous quest

Hello,

Just wanted to know what happend to arcanic’s drop rate?
I spent my last hours (days) to try eaning these ghost stones. Is it normal to make over 200 fights for only 5 of it? Seriously? I’m lvl 1213 and I never noticed that difficulty previously (Maybe was I lucky last times). What is surprising is that at the same time I got more celestial whereas they are supposed to be more rare. What is the next step? Arcanics will only be avaible in paid packs?

Why not ensure that they are guaranteed after a while?

Best regards
MiKa
