Can we normalise making teams you like?

I understand that making the most powerful teams is a key part of the game but I still think that the fun stems from customising the team with your favourite characters. My highest rated character is Rex Splode, who people think isn’t a good character, but he’s my favourite so I don’t care, if I get a character I like than I will level them up to get them in my team just to see them in action. Thoughts???
