I'm saying if you were playing in serious competitive play against other people and your goal was to win, you'd never use Flareon.
In the story mode of pokemon and afterwards, you can use any pokemon you want. Even Spinda, possibly.
I'd still use it if it were in my regular party XD
Because I'm never really competitive. I just do things for fun. Which is why I guess I kinda like certain pokemon "for fun". I never really try that hard to win at anything if I'm playing against others...
