Umm its really shame that the events backfire so much on the rewards section.. You usually on games feel happy when you accomplish something, here… Umm well not so much 
Main problem is the flood of 2* crap non stop…
That crap is worth 250 iso, you know? don’t chew it, just swallow 
I’ve thought that a lot over the last few years. A silver cover isn’t much to get excited over. Seeing as how we only win around 2-5 of them per even, it would be great if there was a higher chance to get a better prize from them. It really hurts to spend HP on them, only to get 250 ISO.
The return on investment spending HP on tokens is very small. You’d be better served saving it for shield hopping or roster slots. Or, if you’ve got tons and no reason to spend it there, save up for a 40x on a vault.
I will spend on vaults, but only the daily deals @ 100. That’s a decent price for a lotto ticket.
