I think that items artificially enhancing champions kits are unhealthy
I define natural enhancement as adding stats to a champion to boost his power.
Meanwhile there are items like Rageblade, Spear of Shojin, Zhonya's who alterate the way certain champions' kits work.
First let's talk about Rageblade:
Every 2nd autoattack with stacked Rageblade, 
get Silver Bolts procs, every 2nd auto 
get a double strike, fully applying the on hit effects from E and items;
How to change Rageblade: *Phantom hit no longer grants extra stacks of anything, if you have bonus on hit that is up at all times(like Kayle E, Tahm passive) you double proc it on 2nd autoattack. Else Rageblade Darius should apply 2 stacks of bleed on every 2nd auto;
*Still fully works with items like BotRk, Nashor's, Bloodrazor etc.
*Price reduced; Hopefully the stacking AD/AP back
Next on the menu, 
:
Burst reliant champions, with little counterplay in 1 vs 1(like 
and 
) are gated by their cooldowns, who stop them from doing damage after a point;
Spear of Shojin allows them to increase their DPS with autoattacks, which in itself would be okay, but before the effect after ulting fades, they get another rotation of spells up; it's kit enhancenent at it's finest, boosting these champions above their capabilities.
Only solution: removal of the item from the game, the game existed before and will exist after Spear, no big deal; the abusers(and yeah I love ya Jax, but you are too good with this item) will still be strong champions regardless;
Last, but not least, 
doesn't interact with on-going abilities anymore;
No Morgana-R-Zhonyas, no Fiddle-R-Zhonyas, no Vladimir-R-Zhonyas right before he dies, comes back with full HP. You have chosen protection over committing to your ULT, live with your decision. You no longer damage people without them being able to damage you back
This item makes mages, that are dumbly safe, even safer and it can also be used offensively, no thanks!
Honorable mention to 
/
becoming melee only, no more 
abusal, you just go 
if you want damage.
is your core item and it's just damn good on you regardless.
