I'm feeling really burned by the RNG loot box system, yesterday I hit level 60 with another character and I dreaded opening it, knowing full well it would be crappy returns, which it was. I want to play your game Bazillion, I was happy to give you money but after getting jack shit from $20, I can't justify any more, so now to get the character that I want, I'm rushing through the game trying to hit level 60 with all the cheap character in the hopes that I'll get enough marvellous essence to purchase Gwen.
I worked it out last week, Spider-Gwen was $15 on the old system, between unlocked/$20 worth of loot boxes, I believe I'd opened about 15, if I don't want to spend another penny and I continue to have terrible luck, I'd have to hit level 60 with fourteen more characters to have 140 marvellous essence. As evidenced by every other person unlocking her on this page, if you have average luck, I'm sure the system is fine but if you have bad luck, it completely fucks you over.
