so, riot, before you consider nerfing j4.
let's just compare his kit to lee sin's for a second here.
Jarvan = a fairly constrained mana-pool lee sin = energy. lee can spam his abillities more often.
Jarvan passive: deals 10% of their current Health on aa with a 10/8/6 cooldown
lee passive: on abillity use, grants 40% attack speed and 15 energy per aa for two auto attacks.
this is the only arguable place where jarvan's is better in most siturations, as 10% of their current Health is quite potent, though it does have a long cooldown early, lee can use his far more often than jarvan's.
Jarvan q= Physical Damage: 70 / 115 / 160 / 205 / 250 (+ 120% bonus AD) Armor Reduction: 10 / 14 / 18 / 22 / 26% RANGE: 770 COST: 45 / 50 / 55 / 60 / 65 mana COOLDOWN: 10 / 9 / 8 / 7 / 6
Lee q= Physical Damage: 50 / 80 / 110 / 140 / 170 (+ 90% bonus AD)
- Physical Damage: 50 / 80 / 110 / 140 / 170 (+ 90% bonus AD) (+ 8% target's missing health) (in total, Physical Damage: 100 / 160 / 220 / 280 / 340 (+ 180% bonus AD) (+ 8% target's missing health)) ) RANGE: 1100 COST: 50 energy / RANGE: 1300 COST: 50 energy. COOLDOWN: 11 / 10 / 9 / 8 / 7
Conclusion: lee's q deals far more damage than jarvan's q, dealing 30/45/60/75/90(+60%bonus ad) +(8% of target missing Health) while also comng with a free dash in exchange for a piddly second more of cd, while jarvan does have the armor reduction advantage, it mostly only comes into play against tanky targets.
Now, to compare their shield-abillities. Lee w= 40 / 80 / 120 / 160 / 200 (+ 80% AP), 700-range dash to friendly targets, four seconds of Life steal & spell vamp: 5 / 10 / 15 / 20 / 25%. cost 50/50, cd 14/8
Jarvan w= 50 / 90 / 130 / 170 / 210 (+ 20 / 30 / 40 / 50 / 60 per nearby enemy champion) 300 range aura. COST: 30 mana COOLDOWN: 20 / 18 / 16 / 14 / 12
Conclusion: jarvan has slightly better shield, by about 10 at base value, thougth it does get even greater per enemy champ, with a weak slow of 15 / 20 / 25 / 30 / 35%. in return, lee has a free dash, better cooldown early-midgame, and a ton of free lifesteal/spellvamp.
Lee e= Magic damage: 60 / 95 / 130 / 165 / 200 (+ 100% bonus AD) RANGE: 350 COST: 50 energy COOLDOWN: 10 Gives four seconds of true sight / Slow: 20 / 30 / 40 / 50 / 60%.
Jarvan e= (permenant steriod) Armor: 10 / 13 / 16 / 19 / 22 Attack Speed: 10 / 13 / 16 / 19 / 22% (abilllity) Magic Damage: 60 / 105 / 150 / 195 / 240 (+ 80% AP) Attack Speed Aura: 10 / 13 / 16 / 19 / 22% RANGE: 830 COST: 55 mana COOLDOWN: 13 Gives him his only mobillity, knocks up by 0.75 of a second by targets hit in his path.
Conclusion: Lee's e has compareable cc to jarvans while being easier to hit, and equal to better damage at 0/10/20/30/40 bonus ad. in Exchange, jarvan has the passive steriod with 10-22 armor and % attack speed as well as the aura on the flag. gives jarvan his only mobillity together with his q, making him spend two abillities with decent cooldowns to dash, while lee has dashes on two abillities.
Lee r: Physical damage: 200 / 400 / 600 (+ 200% bonus AD) RANGE: 375 COOLDOWN: 90 / 75 / 60 knocks 1200 units back, if they hit champs on their flight, they're knocked up for a second, taking the same damage.
Jarvan r: Physical Damage: 200 / 325 / 450 (+ 150% bonus AD) RANGE: 650 COST: 100 / 125 / 150 mana COOLDOWN: 120 / 105 / 90 makes a 325-radius crater that can only be passed by dashes or flash. lasts 3,25 seconds.
conclusion: lee has far greater single target damage as well as 30 seconds less of cooldown. jarvan's has arguably more utillity, and is easier to land the damage on multiple people than lee has, making it fairly equal in the end.
i really dont feel that jarvan should be nerfed, given that lee sin is pretty close to equal or better kit-wise than him, with also being able to use his abillities faster
