Why it’s so hard?

I don’t mean to over complain “is this how you said it?” But this game hard to farm almost everything. Like why all the characters need the same resources? And the Orbeyy! Omg im like 80% something to finish everything in this game patch and I just have 27k orbey! I think it’s impossible to grt 120p from just farming the patch to get the character you want if you aren’t lucky and had to go up to 120p. I really hope I get lucky next time 😖
