I'm enjoying this, but didn't get the memo on re rolling, so I'm using fairly unimpressive 1-3 star characters I've leveled up through battles. I have one character at 3 bronze stars and leveled up somewhere around 13-15. I just got a one star silver of the same character. What's the optimal way to handle this? Do I feed the 3 star bronze to the one star silver? I do I keep the leveled bronze and feed the silver to it? I get that losing a higher star character will increase the stats for the silver character in this case, but what does the bronze/silver/gold tier really mean?
I hate that I'm enjoying this. I know it's not great.
