@Riot Why are some champion/item combos allowed to stay while others must be removed?
Look at 
Okay, I'm pretty sure you are familiar with how Lucian's "The Culling" works.
If you don't, then it works like this:
"Lucian fires a barrage of single target projectiles in a straight line, dealing physical damage over 3 seconds. The ammount of shots fired scale with Lucians Atk Speed and it deals 400% damage damage to minions."
Now let's look at
Toggle.
"Single target spells and attacks consume 3% of current Mana to deal bonus physical damage equal to twice the amount of Mana consumed."
According to both definitions, The Culling should proc Muramanas active. Regardless of how "broken" it could become, it just should.
Now, you are probably thinking "The Culling doesn't proc Muramana because The Culling doesn't proc on-hit effects", which is true, yet Muramana, despite feeling like an On-hit effect, procs on every single target ability in the game, no matter if they proc On-hit effects or not.
Acid Hunter doesn't proc on hit effects, yet it procs Muramana.
Unleashed Power doesn't proc on hit effects, yet every single ball procs Muramana.
Spear Shot doesn't proc on hit effects, yet his spears proc Muramana.
You see what I mean? The Culling is probably coded as a bunch of Acid Hunters firing in one single direction very, very fast.
Therefor, every single shot should proc Muramana.
Now, does anyone remember Sword of the Divine?
It used to give a champion 100% Atk Speed for his next three shots.
It didn't give any stats when it was on cooldown and was trully a niche item that was used to "exploit" elements of the game, despite not really being "exploits", just combos which were too good.
However, those 100% Atk Speed weren't taken into account for The Culling.
Just why? The item was a niche item already, it was powerful on champions like Draven, Rengar and maybe even Vayne, but that was it.
You never mentioned the fact that "The Culling" doesn't take SotD Atk speed into consideration, which is something that bothers me because it should. There is no reason as to why it shouldn't other than "maybe it would make him 2 op".
Because if it really didn't work with Bonus Atk Speed coming from Items Actives, The Culling wouldn't work with
Active.
Yet it does and always did.
The item has been removed now, so there's no way of fixing it, but it just bother my mind that the best way found to make the Champion less Reliant on something was to completely remove that mechanic.
I remember someone saying Riot didn't want Lucian to become too reliant on certain items.
But then again, how comes:
can still cast Safeguard on Wards coming from 
,
,
and others case use their
without interfering with their Ultimates.
with 
and her
which proc on every single Slash from her Blade Waltz. She will also die instantly if she ults a team with 5
because of this.
And many others I didn't mention here.
Aren't these cases the exact oposite of what you wanted?
Regardless, this isn't a QQ thread or a "buff dis pls" or a "nurf pls 2 op".
I'm just wondering why some item combos are allowed to stay and others are completely removed without ever being mentioned.
