3 star upgrades?

I realize it’s kinda pointless to upgrade 3 star and below champs once you get past a certain point, but do you guys at least sell those low lever catalysts? Just seems like a waste sitting there not being used

It is not pointless to still rankup 2* and 3* heroes. I still do that during some Solo Levelup Events if I’m not in a position (or wanting to) rankup additional 4*/5* at that time. Always get the free 25 Units Milestone during Levelup Event. And doesn’t cost you any valuable T4Basic or Alpha Cats to do so.

So long as you got more ISO/Gold than you will ever need for 4*/5* later.
