I understand the design team wants to flex their creative muscles;
But champions need to be pushed back into their roles.
Battle mages do not need to be bursty.
Assassins do not need mobility nor survivability.
Marksmen do not need damage reduction.
Bruisers do not need Conquerer to remain in the game.
Tanks do not need damage buffs.
This 
should be disabled on champions with a built in dash.
This 
should be disabled for champions with built in dashes or speed boosts.
This 
item should not exist, despite it being my favorite.
This 
should have an MR version.
This 
should have been removed when Riot declared war on Spell Vamp. Either keep it in the game or get rid of it, no half in half out bullshit.
This 
should have a <1000GP component that provides Grievous Wounds for laning against sustain enemies as an AP champion.
This 
should not be more valuable than 
. Summoner spells should be THE most useful effects in game.
This should be able to be cast on allies.
This and 
should consistently apply the same effect.
This 
should have an AP version, and this 
should have an AD version, and the Zhonya items or QSS items should go on CD together if one of them is used, no double Zhonyaing or double QSSing.
This 
should favor neither AD or AP, and be an item slot sacrifice, not something core to your build.
And finally;
EVERY champion should be able to be itemized, or have summoner spells that counteract their abilities. 
should apply slow/damage reduction unless an equal exchange of occurs, that means no no no 
no 
, you are SLOWED and your damage is REDUCED.
Tl;DR:
Push champions back into their roles. Make summoner spells stronger. Fix items. Nerf damage across the board. Stop buffing for skins sales. Maybe you'll finally pass your 2016 sales numbers if you make the game fun to play.
