Suggestions from a new player who was an old player

As a new player, I’ve seen some of this too. Particularly the credit and ability mats. I’ve been using the Bad Batch to advance throughout the game, and I’m constantly running out of credits and purple mats. For about two weeks, I had five characters I could seven star whenever I wanted, but could never get enough credits. It’s not unbearable, and the grind is part of the fun, but I just wish credit and mat drops could be accelerated as well.
