Balance Needed

there are many things that need to be fixed with this game, here are a few ideas that you should strongly consider

1. veigar's stun cage should spawn around him in place instead of him being able to put it away from him and catch people on the other side of his lane
2. if someone loses their promos they are set at 75 LP but if they win they are set at 0. either make it so losers are set back at 100 or winners are put at 25 so they dont just get auto demoted again
3. Zoe is too strong right now, you need to nerf her in some way because she is 100% pick/ban for not only pros but at basically every elo. the reason for this is she can do 3k dmg with her q which is on a 3 sec cd....please tell me how thats fair.
4. abilities that apply on hit effects should not grant things from kleptomancy, such as ez q or gp q.
5. illaoi should not get kleptomancy stacks from her e spirit
6. do something with glacial augment, it is useless
7. zoe w should have like a 60 sec cd and have the ability to drop unwanted spells
8. cho's ult should not do true dmg, same as darius
9. ryze ult shouldnt work if hes in zon or stopwatch
10. Lucian shouldnt be able to auto while casting abilities
11. mord should have to cast his ult on dragon to get the spirit
12. master yi passive shouldnt stack with rageblade
13. cait's headshots shouldnt have increased range, or her traps need nerfed because being able to place 5 in a matter of seconds is insane because its impossible to seige
14. champions that scale with defensive stats like malphite, voli, mao need to have their ratios lowered because it makes no sense to do more damage as you get more tanky
15. champs like ziggs or zoe need their abilities to cost more mana so they cant just spam them in the early game and auto win lane
16. singed needs to be reworked because people just proxy with him and then feed and all the farm goes to waste because they just snowball their lane opponent
17. gp ult shouldnt be global, should have a range like panth or tf
18. blitz hook should pull himself to the enemy, not the enemy to him because if he lands one hook out of a thousand its still a free kill
19. jax shouldnt be able to auto during his e since his staff is twirling above his head
20. champions like veig or nasus should not be able to infinitely stack, there should be a cap
21. brand passive needs a huge nerf becuase he already has 4 high damaging abilities, he doesnt need an aoe nuke on top of it
22. mundo clever should not do hp% dmg, should just be a base amount
23. teemo shrooms should expire faster
24. zileans ult should not be affected by his ability to take seconds off his abilities
25. taric ult should not go off if taric dies these are just a few ideas off the top of my head that should seriously be considered, i did not use bias for what champs i talked about and im sure i could do more but these issues are just what stood out to me
