Have limited catalysts to do a single rank up. Would you take one of the following 5* to max (Hercules, doom, ghost, torch, quake, nimrod) vs. One of the 6*s to rank 2 (ie bishop)
5* hercules, you will be able to dupe and max sig him easier with each side quest giving access to awakening gems. In fact you should get the one available in the current side quest.
A 5* r5 sig 1 Hercules is just the same as a 6* r2 champion. And Hercules is arguably the best champion in the game.
A 5* r5 max sig Hercules will match up with a 6* r3 as well.

If you haven't done them, go back and do the earlier variants, they rewards 5* rankup gems
1. God tiers
2. 6*
Some 5* are definitely worth it, even for questing. I had 5* in my act8 exploration teams.
Now, if I could only remember to stop banning AA in BG's.
