good attempt at a support jarvan, an idea I happen to like. I didn't like your item or spell choices much, but hey you can't have everything.

Thanks for the advice man, I'll change my guide accordingly. :D

Finally a support J4 guide. Right I'll give you some constructive criticism.

Your early game build is good but I would honestly stay away from items like Trinity Force and Frozen Mallet unless you manage to s***bag all your kills from your ADC. As a support J4 it's your job to be tanky and provide utility over damage. He can do that very well. We all know he's capable of damage, but then again so is Blitzcrank. When support, build as supports do.

I think the early Aegis of the Legion and Ruby Sightstone are excellent ideas. I think a Locket of the Iron Solari would synergise really well with Cataclysm. Randuin's Omen, Shurelya's Battlesong are both good ideas. I have a feeling an early Vampiric Scepter into Zeke's Herald would be nice, but it's expensive. They're all up for debate I guess. Oh, and I wouldn't take Sunfire Aegis, Atma's Impaler or Maw of Malmortious.

Your masteries are very good. For your runes I would consider switching your ArPen marks for flat AD, or additional armor as they seem to work best on tanky supports right now.

I'm thumbing up the guide because aside from my personal disagreements, it's good and I enjoyed reading it. Keep up the good work.

Thanks man. :D

I like the idea of using J4 as a support and I like your guide, so upvoted!
