Why can someone still re-roll a champion after someone else re-rolls it?
Just had an ARAM lobby where someone re-rolled Udyr (for Kha'zix) then I rerolled my champion and got Udyr.
Why can this even happen? As far as I'm concerned, when someone re-rolls a champion they're re-rolling it on behalf of the entire team (otherwise they'd obviously trade it to someone who wanted to play it).
