Using Master Balls on catch rate 3 legendaries is perfectly understandable, so just really do what you want.
Anyway, I just wanted to let everyone know that the challenges are optional... you shouldn't feel compelled to do them. If you are too busy, you don't have to do them. I understand completely. I don't want this pastime to feel like a job to anyone so if you cannot do a challenge, please don't feel down or anything. It's fine. We're here to have fun and I'm not interested in making anyone not have fun. I am open to suggestions for the club at all times (by PM if you'd prefer), so just keep that in mind. Please everyone, remember that this is fun. I apologize to all of you if I have pressured anyone into challenges and I will look towards a future will I will keep a closer eye on things like that.
Good luck and ultimately, have fun, because that's what this club is all about -- fun.
