Iso8 expiring, help

Mocaman

i have 3k iso bricks expiring, and i dont have the catalysts to rank up the champions i want to level up. Is it better to dump those bricks to other champs (that i dont rlly use) or just sell for gold. I'm not that high lvl btw, just lvl 50 and still exploring act 4 before tackling act 5

if you grind arena, it's definitely worth it to get more champs to rotate, but selling it is a good option if you're low on gold and you have no use for other champions besides your a team

Do daily class quests and use the t3 cat to rank up your obscure 2*, 3* and 4* champs for fun. I plan to do that when I have enough high-ranked champs
