With frustrating regularity, I see allies setting 1* or 2* (level 1) units as their leader, which makes them pretty much useless to all of their allies. Can anyone explain why people do this? Often it's during events, when we need strong allies the most - I just don't get it.
Is it a rank thing? They've attained a high rank in the event, and figure setting a weak leader will prevent their allies from potentially doing well enough to pass them?
Or is it just a douche move, for no real reason?
Honestly, if there's a good reason to do this, I'd love to understand.
