SAying that it's "totally doable" to get in without killing a mage is pretty misleading, if not outright false.

1. Most battle leaders won't even consider an applicant that's never killed a mage (nor should they).
2. Even if a battle leader WOULD consider inducting someone that can't kill mages (again, this isn't a given), it stands to reason that the interview/approval process would be much more in-depth and thorough.. this adds up to just another roadblock for a newer player.
3. You said yourself, you have no idea if its technically possible. The entire attempt could be a waste of time.
