An Idea To Preserve Champions After Their Rework
Have it so that during champion select, you can select either reworked version or pre-reworked.
Of course each version will have slightly different models to differentiate between the two for easy game play readability.
This way, we can increase champion visibility (in terms of frequency a champion appears in a game) while giving it more than one role when a champion receives a drastic rework (
MORDEKAISER COUGH) .
This is also good news for the developers because you don't need to create a whole new champion to implement your ideas. It's a win-win situation!!!
