Day 1 player. I have 92 5* in total (including some dupes, f2p rewards and promoted ones). If I were to remove heroes that I used money for, I would end at 81, because I'm guilty of spending money on seasonal heroes.
Keep in mind that around 20-25 of the are promoted to 5* from either basic 4 summons or from GHBs. Subtracting those gets us to a 5* summoning luck that seems kind of average to me, when I compare it with my friends.
20-25 is definitely a correct estimate, therefore if say-you upgraded 25 then that leaves us with 56 5 stars that are summoned at 5 stars already. Given that, you're already absurdly lucky.
