and it looks good to me.

getting you back from jet trolling.

Not bad, even though I think Flash is essential.

I don't play Jarven, but the build seems solid, you write well, and above all, the guide is PRETTY. Well done.

See above.

Good changes, see you placed Flash higher up in useful summoner's.
I'll give you a +1.

Thank you for the well thought-out response. I'm gonna play a few games laning with the Philosopher's Stone and try again with the Trinity Force.

Even though Jet sounds like he's angry as hell, he has some points.
I play Jarvan pretty often, and your build seems rather strange to me.

1. The build is more focused towards DPS than towards tanking.
2. You're using Archaic Knowledge , even though your two main damaging spells are physical. I'm assuming you took it for the passive, but I don't think it's worth it.
3. No Philo stone. As you said, you're mana hungry. Since you're 9/21/0, you don't have any extra mana regen from masteries or runes. You're going to need a Philo stone, really. Don't underestimate what a Philo stone does for you. You even get most - if not more - gold back when you finally sell it (with the extra passive gold).

Starting with a Regrowth Pendant + potion, then buying a Philo stone pretty quickly really helps out your laning and gives you a small boost in gold.
I also play with 9/0/21 or 0/9/21 depending on the enemy team, because I find Jarvan to be a great initiator, but as a tanking role you need the CDR and such. But that's just my personal choice.

I'm not voting right now, because I'd like to hear your ideas about what me and Jet wrote down. But it's currently leaning to -1, sorry.

EDIT: Even if you build full tank with just one or two dps items, you deal out a ton of damage. I mostly go all tank except for Trinity Force and possibly a Wriggle's Lantern. The burst with a triforce is insane.

Pretty good build , being tanky aswell as being dps . What every Jarv should be, Usually.
Great Job. (:

the core jarvan item is the last in your build

no regen / no philo stone means your laning is going to suck easily

aegis + frozen mallet + wits end what the ****

no flash = not allowed to make mistakes using your ultimate + no real escape after your e+q. flash also good for making surprising ultimate jumps

don't like the masteries either - why build a dps orientated build but run 9/21?

actually, you said flash is a bad summoner spell, not going to bother commenting anymore

Wow... simply... just wow.... Incredible job on the guide! I mean this has to be one of the most complete, fonctional and good-looking guide I've seen, like, EVER.

I honestly tried to find some criticism and all I think is missing is a Tactics section showing some tricks&tips. Here's a freebie: Ulti on a melee and flash/charge-less champion, throw down your Standard and charge out. Your giving a kill to your carrys and your still in front of the line and mobile, ready to tank. I know it's not the best use of an Ult, but it is unconventional and surprising.

All in all, Good Job. Seeing this is your first guide, I hope this isn't your last!

Assuming you read down this far, thank you! Please be kind enough to vote and add your thoughts in a comment :D
