i typically like to use at least one or two non-ou pokemon if only 'cause most good teams are at least a little out of the ordinary...unless they're stall but those don't take any skill/aren't fun :(
I do wonder why they made the change though. Wouldn't it be easier for LC people to just use a LC tier tab instead of making the rest of the site impossible to navigate? You can change the preferences but you have to change them every time which is annoying. I mean does Axew or Happiny really need to be on the main page come on
