He could literally run probably 20+ players on his roster and still place top 5. Just makes no sense to me to spend all that money and not get enjoyment from trying new things and using them all.
I could spend all those purples and credits in about 60 seconds. I like to wait till I have characters max geared up first before I lvl and ability mat them.
It's a big reason why I'm choosing to farm all the ewoks since it will take forever to star them and I won't be using my credits or mats on them at this time. That way when update comes I have everything saved up for my current roster and can stay ahead of the game.
