For the love of 20 ISO....

I just don’t understand why ISO rewards are not tiered in this game…

I’m sure this has been said a thousand time but REALLY?!?! 20 ISO for winning a fight against Level 190 Wolverine and his 190 Ninja Super Pals?!?!

I’m working on 3 to 4 star progression, working now to max out my 3 star levels. Needless to say, the 20 ISO’s is really an insult.
Please somehow tier the rewards to match the level of the fights we are participating in.

Having survival nodes revert to only a single 20 ISO reward after the first pass is an extra slap that could be corrected also.
