What thing i don't like about League of Legends [Changing]

I mean i like the champions and everything new in this game but im tired of changing. Old players are used of playing their main champions and when it comes time for a rework everything is ruined. With every update i feel like im getting bored of this game because the champion that i know from a long time got changed. Everybody liked the old gankplank,old galio,old fiora.Back in those days people played Alistar Jungle and it worked really well compared to what is right now - he is forced to be in support role.

The game is changing so fast and i dont like it, new things come up like - items,runes,reworks, a bunch of patch notes. You can hardly memorize that patch notes and stick to the gameplay. I know that riot wants to bring fresh new things for the game i tottaly understand that. But the thing is that - people stick with one champion , learning its mechanics and abilities and in the other day the champion is getting reworked. There is no time for learning a specific champion because soon or later its getting reworked or updated. The New Rune system is pretty good but i feel it doesnt give you many options. Because the old one was giving you a chance to put attack damage,ability power,movement speed,attack speed,even make death timers lower. I know that the new rune system made the game more optimized but i just feel it doesnt give you more like the old one
