The nature of champion updates
Nothing big and I don't know if this has been answered already, but I'm just rather curious about what delegates the priority of which champions get reworked?
By reworked, I mean noticeably different from what they once were and what they used to play like. Champions like Ryze and Poppy, for example. Though, visual updates are also worth mentioning.
Is it a matter of what champion seems most effective to work with, or one that just seems like they need to be flushed out properly?
