I’ve always found it strange that when spending money on the game I have to choose between HP and Iso.
Personally (and I’m sure if people agree/disagree they will say) It would make more sense if HP is the ingame currency, to use that to purchase Iso.
So if I’m missing a cover or 2 to max out a hero and want to get the Iso too, I don’t have to make 2 purchases.
Also means that when I purchase HP, I know I can spend it on whatever I need.
It might only be a small change but I just think it would make things a bit easier for a lot of us.
