please help JARVAN 4

hello, i really like to play jarvan but i think he has too many flaws to be called way more than counterplay: his early game jungle is one of the worst ive ever seen ,he can oom ,i almost died to blue after gromp in 2nd games 2 times i witnessed jarvan being godly in jungle: when there was only lee sin and jarvan with warrior preseason i think ,and when there was bulwark item and jarvans flag gave armor to his nearby team ;currently he doesnt even give armor bonus to himself ,making him very weak early,not even close to being good early

why he went down? 0 from 10 / 13 / 16 / 19 / 22. then in 2 diffrent patches u gave 5 base armor back long ago : E: Active no longer grants bonus armor.(when bulwark was an item)

compared to other go-to junglers what jarvan doesnt have ? SUSTAIN ,right elise heals ,gragas heals,rek`sai, lee sin spell vamp lifesteal and shield to mitigate dmg from enemy/monsters

that being said ,would be too strong that when E or W is active to have a sort of sustain ,not much ,but anything matters also ,compaing his damage to lee sin feels lack luster,his EQR does 270% BONUS AD,while the blink monk has 480% bonus ad dueling power

can you make E have some ad ratio or W some bonus/max health % ,because shield is very weak ,maxed last gives 50 shield +20 per champion but that is easily destroyed and very inefficient

or revert knockup radius Knockup collision radius reduced to 180 from 260. i hit a tristana literally on the flag and didnt knock her up ,for reference can you tell me the 180 radius of jarvan compared to yasuo Q?

his passive is barely used 2 times a camp ,has no scalling ,and isnt even useful on low health enemies since it is 10% current ,some kind of weaker botrk passive with CD

one suggestion would be to lower his costs ,make Q deal 150+150% total ad damage ,to make his game more fluid ,because i think anyone can confirm that his damge is extremly low if he goes full tank.make his passive apply more often, have a scaling or give some health back like xin id rather have passive 3 hit instead of 1 hit burst ,10 seconds nothing warrior enchant +5 should have bring him back but that wasnt the case ,since if he must recall that much early ,he loses alot for an early game jungler,because he has no armor or sustain

also was 3v3 god a time ,with leona-jarvan lockdown but then ,you nerfed him ,and more and on crystal skar ,why?reducing pure innate power

V4.15: (Twisted Treeline & Dominion only)

Martial Cadence Per-target timer increased to 10 / 9 / 8 seconds from 10 / 8 / 6. Dragon Strike Armor shred reduced to 10 / 12 / 14 / 16 / 18% from 10 / 14 / 18 / 22 / 26%.

thanks
