Proving Lee Sin is numerically Overpowered by comparing him to every other Warrior Enchant Jungler
TLDR AT BOTTOM AND LOTS OF MATH WARNING SO MUCH MATH WOW
built on AD Junglers that usually build almost full tank after this item
The following is each AD Jungler that fits this criteria listed in order of their damage increases from this item
240.75 more damage with abilities (80% Bonus AD + 455% Total AD Ratios)
225 more damage with abilities (500% Bonus AD Ratios)
216 more damage with abilities (480% Bonus AD Ratios)
171 more damage with abilities (380% Bonus AD Ratios)
166.5 more damage with abilities (130% Bonus AD + 240% Total AD Ratios)
141.75 more damage with abilities (195% Bonus AD + 120% Total AD Ratios)
141.75 more damage with abilities (300% Bonus AD + 15% Total AD Ratios)
121.5 more damage with abilities (270% Bonus AD Ratios)
117 more damage with abilities (80% Bonus AD + 180% Total AD Ratios)

both have health damage, but the latter doesn't have to work for it and has higher ratios
all have high ratios and damage potential, but the former 2 have to channel their abilities to deal that damage
Lets now look at base damages of those AD ratio scaling abilities for the top 3
1190 (Q/E/R)
1140 (Q/E/R)
545 (Q/E)
Now lets look at the top 2 in terms of base damage ability potential in 1 second
590
1140
In 2 seconds
790
1140
In 3 seconds
990
1140
In 4 seconds
1190
1140
So this calls for a direct ability damage comparison between
and
since they deal the most damage with both ratios and bases in an AoE
Q:
9/8/7/6/5 CD, 150(+10% Total AD) as an enhanced auto against one target
Q:
11/10/9/8/7 CD, 170(+90% Bonus AD) + 170(+90% Bonus AD)(+8% Target's Missing Health) to one target
Lee's Q is higher range, lower CD for most of the game since Wukong maxes Q second and deals FAR more damage than Wu's Q
E:
8 CD, 240(+80% Bonus AD) Physical Damage to 3 targets maximum but is a gap closer
E:
10 CD, 200(+100% Bonus AD) Magic Damage to any targets around him
Wu's E potentially does more damage and gives him AS, but Lee gets AS every time he uses an ability technically. Wu's E gives him a gap closer that he didn't have, but its targeted and not freeform like Lee's Q and W. Still giving the win to Lee here.
R:
120/105/90 CD, 200(+110% Total AD) Physical Damage per second over 4 seconds for a maximum of 800(+440% Total AD)
R:
90/75/60 CD, 600(+200% Bonus AD) Physical Damage to all targets hit
Both provide a knockup, both provide high AoE physical damage. Lee R is always a lower CD by far than Wu's R. Wu can deal more damage than Lee's but he has to hit a Champion for at least 2.5 seconds to deal more damage than his R.
TLDR:
abilities are faster, lower CD, easier and better than any of his competitors like
and
that have to extend and stay in an area for an extended period in order to out damage him
vs
vs
isn't on that list.
