Mainly because a gold flash from a Standard means two 3* covers now, I’d imagine. Not that spending ISO on Standards, even then, is a GOOD use of resources, but that way if they ever release a new 3* again, you won’t be able to whale one up to champion status with nothing but ISO.
Durr, I guess my
aren’t championed. But all my heroes are leveled as far as they can go.
As far as I’m aware, I can only use ISO to level/champion my heroes or (I used to) buy standard tokens. I can’t level my heroes more unless I get more covers/tokens. What else is there to spend ISO on?
Playing the Deadpool Daily Quest, I get 8-10k ISO and one or two
cards daily. Since my
are championed (mostly), I don’t need ISO to level them and it just sits there. I was starved for a while when I was still getting them up to champion, but now it just builds up quickly. I only make a dent if I randomly get a
or
cover.
(I built up about 60,000 ISO in the last week and a half, including dropping 30,000 to level up a
cover I randomly got.)
Yup, just save it. It takes over 300,000 ISO to fully level and champion a 4* character, and nearly double that for a 5*. Even just considering the 12 4s available in tokens, that’s nearly 4 million ISO (give or take) that you’ll need to be saving. And they release a new 4 every two weeks, except for the ‘breaks’ when they release a 5* instead.
