I Have a suggestion!
I think that riot shouldn't rework champs they should create a new champ and give it a different name. Because there are some people like Benjore who had 3,200,000 mastery points on Galio and he got reworked so he could never play old Galio again. Now I understand champs like gangplank he really didn't even have much of a rework just 2 moves changed. But champions like Urgot there were people who mained old Urgot and he got reworked so I say that you shouldn't rework champs you should just make the new champ with a different name
