But then I started to enjoy it since it was "hard mode" compared to the easy catch of a great and ultra ball. Balls in Gen 2 weren't very useful due to apricorns being rare, although catch balls are also easy mode for roaming legends, so they are boring.
I didn't play modern pokemon much until Gen 5, then I tried powerful balls like dusk and they are so easy they are super boring.
