Someone give me reasons why this doesn't work.
So I did, How Effective Items Are Including There Passives. (this is for AP champions :)
:112.1%
:116.9%
:79.71% before AD 120.9% after AD
: 127.7%
: 139.9%
: 146.4%
: @480 Damage= 100%, @500 Damage= 101.4%, @750 Damage=120.3%, @1000 Damage= 138.9%, @1250 Damage= 157.6%
Although this item should not count since it takes into account outside sources. Its flat value by itself is 63.87% But this number would be doing this item a very bad wronging.
If you are questioning how I calculated the following I will explain here.
For the Slows on
and
I took the base movespeed of 25 for 300 gold. Multiplied by the slow factor. So 60% or 40%. Then I took that number and multiplied it by the Gold Per Stat. Then multiplied by Duration of the slow MAXed. meaning that for
if you hit all 5 targets you get a max slow duration of 2.5 Seconds. Vs
2 Seconds.
The math looks something like.
300/25 = Gold per Stat 12, 25 x (.4 or .65)= movespeed LOST. (Movespeed LOST)(Gold Per Stat)(Duration)
So let test this with
(25 x .65)(12)(2.5)= 487.5 Gold
Testing this out with
you get (25 x .4)(12)(2)= 240
Again remember that this is set to MAX capability since some items are always 100% effective under all conditions such as 
Now for the damage Calculations and Catalyst.
I set them to the highest value that the item by itself will offer.
So (highest value + % x AP on that Item) / 150 For HP Stat x 400 For Cost of HP @ 150.
(200+28)/150 x 400= 608
((150 + 15) +16.5 x 5 (for additional Bolts)) / 150 x 400= 660
(250+24)/150 x 400= 730
Why did I use HP instead of AP or AD for damage. Its because Each one of those points are of Damage which is taken away from HP, this is saying that they take 100% of that damage. This is the value.
Finally for Catalyst; it was very simple.
Take Max HP from item x .15= Mana from item x Gold Per Mana Stat. Take Max Mana from item x .2= HP from item x Gold Per HP Stat.
So in short.
@500 HP and 400 Mana; You get 75 HP if you take the whole HP bar of the Catalyst, and you get 80 Mana if you spend the whole Mana bar of the Catalyst.
Math Looks like. 500 x .15=75 x 2.666 Continuous= 200 Gold
400 x .2= 80 x 1.4= 112 Gold.
Value of the Catalyst passive is 312 Gold.

Applying the same math as above you get 60 HP and 52.5 Mana which results in 233.5
please tell me where the math could be wrong.
Edit 1:
Forgot to mention how I did the shield.
150 (base) + 200 (from 20% max mana of
) /150 x 400 = 933.33 continous
Edit 2: * come up at italics... So replaced all * with x
Edit 3: Forgot to mention the 20% mana on Assist/Kill on 
400 x .2= 80 x Max Numbers of Kills or Assist (5) = 400 x Gold per Mana Stat (1.4) = 560 Gold
TL;DR nerf Morellos :)
