man.... you play like me :) jarvan is my beloved main and ive tryied every combo possiable :) and here is a little tip from me ! try swith the Force of nature for an Gaurdian angel and the Thornmail for an atmas impaler :) thornmail aint that usefull that late in game :P and atmas gives you INSANE dmg when you combo it with Wormog and Frozen mallet ;)
just a hint ! otherwise your build was awesome :) <3
