It's really about the champ. Wu Kong has built in Armor penetration.
ACTIVE: Wukong's next basic attack within 5 seconds gains 125 bonus range, deals bonus physical damage and reduces his target's armor for 3 seconds.
BONUS PHYSICAL DAMAGE:
30 / 60 / 90 / 120 / 150 (+ 10 / 20 / 30 / 40 / 50% AD)
ARMOR REDUCTION:
10 / 15 / 20 / 25 / 30% of target's armor
Crushing Blow resets Wukong's autoattack timer.
Coupled with penetration items this amounts to a FULL reduction of Armor, sometimes even putting it negative.
+ this skill = 54% possible Armor reduction, up to 34% of it coming up front.
And then you have
.
If wu starts out Duskblade, and a champ has something like 75 Armor, what they actually have is 52.5. And then Duskblade alone drops that to
34.5 Armor
That's almost armorless in one item. If he gets to
at 75 Armor, that's 16.5 Armor.
At 16.5 Armor, you have 14% damage reduction.
Even if you have 200 Armor, Wukong effectively can reduce that to 36 Armor.
Armor doesn't work vs him at all.
And then you look at what his ult does after all that armor reduction.
Cyclone EFFECT RADIUS: 162.5 COST: 100 MANA COOLDOWN: 120 / 105 / 90
Cyclone
ACTIVE: Wukong spins his staff around for up to 4 seconds, becomes Silence iconDisarm icon pacified and gains 5% - 40% (based on time active) bonus movement speed. Reactivating Cyclone cancels it immediately.
The spin deals physical damage to nearby enemies every seconds. Enemies affected by Cyclone for the first time are briefly Airborne icon knocked up.
PHYSICAL DAMAGE PER SECOND:»
20 / 110 / 200 (+ 110% AD)
If he has about 250 AD (point where game starts picking up) His level 6 Ult does 295 damage per second, or 1,180. That's huge for early game....especially vs a target he eliminated armor on. On Level 16 Wu, , he's closer to 400 AD, for a 2,560 damage spin.
Again..... huge damage for all the armor penetration he has.
We've always had Armor penetration/Lethality. What we didn't have was Electrocute doing 30% more damage than Thunderlord's , vs virtually no armor.
His problem is he's not just a Solo duelist or a Team burster. He's both. Solo he can almost 100% eliminate Armor. Team he can eliminate armor on the most problematic champ, and then spin for 2,560 and clean up the rest (of whom will also get massive armor reduction/penetration because of
)
This is why Talon and Zed generally have more counterplay. They don't have built in extra armor pen/reduction. Although annoying and often high kills, they are beat by the rules of numbers. Wu Kong isn't.
