'If you play x champion I main after they've been changed and I've stopped playing them...'
'... you aren't a real x champion main like me.'
Right, because everyone knows that you spot real dedication by seeing who is the first one to abandon ship rather than trying to adapt, grow, salvage, and stick by something when things change or temporarily find themselves in a bad spot.
Clearly if I played old fiora for years and then she got her rework and I still play her and love her, I'm not a 'real' fiora main compared to someone who quit the game or abandoned fiora when she was changed.
Clearly if I've played riven for years, I should immediately stop playing league or change to a different champion if Riven ever gets a significant rework or number adjustment or else I'm not a 'real' riven main.
Newsflash: people can get attached and fall in love with different aspects of the same thing. If I love the idea of fiora/riven, or the lore, or the art style, or the playstyle that revolves around mechanics and timing and high skill caps, or any other thing about a champion then it wouldn't make any sense for me to drop them entirely just because some ability got changed or the best item build is no longer the one I liked the most in the past or some additional counterplay was added here or there. If I love and play a champion for reasons other than their winrate, exact current state of their abilties, or how they fit into the current meta, then of course I would stick with them through the 'tough times' or reworks or anything else that happens.
TLDR: If something happens that changes a champion you like so that you can't enjoy them anymore, thats sad for you but it doesn't mean other people who love the champion just as much or even more than you aren't allowed to still enjoy them and keep playing them.
Main, even after change. Only main him because of the concept alone and it's been this way ever since I first played League of Legends. Besides, the new update's improved his style.
before his rework, i never mained him but i just enjoy playing the rework, same goes for
they dont feel the same, i played them because i enjoyed how they did. With the reworks it felt ruined for me. Just my opinion.
