riot do you really need to rework champions and remove the old ones? can't we play both?
I just feel like unless a champion had series issues there is no reason for riot to not just keep them in the game and call the new ones 2.0 for example old zac was never OP or under powered and nobody asked for a rework yet they removed what made him fun for me at least, his mobility and ability to carry games without having to solely rely on a team, he was an ap fighter who could build full ap. Old galio at some points had the lowest play rate in LOL, his ultimate relied on the enemy messing up or forcing galio to use flash, he had clear counters and was only picked for ap heavy comps or people who mained him, so why remove? Old urgot nobody was calling old urgot over powered. why not just leave them in the game and make an urgot 2.0 legit one of the least played champions who could be good in the right hands.
it's not like riot would have to add 2 stories to the champion for lore or anything, and this BIG indie company worth multi billion dollars can easily afford and easily know how to programme it so that when one of those champions is banned both of them are or just make 2 separate champs, everybody already knows the original champions ability's so why remove them unless they're a HUGE balancing issue?
it took years YEARS for riot to revert leblanc and rengar, I just want old zac back(galio too), I can understand that some rioters worked hard on the reworks and yeah "OH NEAT ABILITY'S" so they clearly don't want to revert them, but like come on, let me play MY FUCKING CHAMPIONS THAT I LOVE, they were never fucking broken. Riot honestly please, if you refuse to revert champions because the kits are nice why can't you just either make it so you can choose which of the 2 champions you want, with clear visual differences and when they're banned/picked both are banned and if one is picked the other can't be picked example zac,
quinn,
or make them 2 seperate champions if they're different enough example urgot,
(maybe yorick) 
I just would really like to understand why this can't be done or better yet WON'T / HASN'T been done.
