A solution to allow ISO to be more accesible
More permanent objectives resetting every day, instead of winning fights in certain ways or clearing certain quests it could be stuff like
Win 5 fights with avengers
Win 5 fights with X-Men
Win 5 fights with GOTG
Win 5 fights spiderverse champions
Etc.
They would give rewards based on what level of progression you are;
Below conquerer - 1PHC
Conquerer - 1 ultimate crystal
UC - 1 Grandmaster crystal
Cavalier - 1 4-6* crystal (same odds as GMCs on the 5+6*s)
This would mean that players, especially UC and above have more access to 4*s and thus more dupes and ISO, it also solves the gold problem as well, ISO can be sold. I just think it’s a simple solution and would be a fun alterior motive to use champions
