Please make the Hextech Keys Fragments drop-able regardless of whether or not you own the champion for the remainder of the event, once the all-champ-f2p reward is unlocked. As the all-champ-f2p is completely nullified by the fact key fragments don't drop if you are playing a champion you do not own, and thus people simply don't play the champs they do not own which is counter-intuitive to the cause.
That'd be awesome.
Or really, imo key fragments should drop regardless of whether or not you own a champion in the first place. But hey.
