Ok, So I start mcoc on my alt, After a week of farming I got 1,500 units, average stuff. I ask noob global what to spend it on and ask if I should spend it on crystals and they say no crystals are super trash never buy them, after a while I get bored of only having 3 stars for my levels and I pop 10 red room crystals for 1,500 units, What I get is insane luck since an 4* is 4%, 3 star is 25% and 4* Nexus is 1%. I got 3 star king groot, 3 star captain america (IW), 4 star nexus crystal which I got quake from, 3 star deadly origin, 4 star deadly origin, 4 star deadly origin again (dupe) I thought my game was bugged (in a good way) But I got very good pulls and this convinces me to spend all my units on crystals
