If you haven't spent anything on the game yet I would ask yourself one question
Are you having fun knowing that you could be doing 'better'?
The point of the game should be to have fun, if you are having fun playing with the family team keep going. If you want to have a side project where you can 'do it the right way' and fight for #1 then go for it. I dropped everything to get Yoda because my nephew wanted to play with him when I came to visit. It slowed my arena goals, but I don't regret a second of it.
I really like this game and we should all play it the way we want and enjoy it. We all get hung up occasionally with this toon is too good, or this table is too hard, but that's not what matters.
To quote Gladiator - 'Are you not entertained!?!'
If you are keep going with whatever decision YOU want to make
