Attack Speed Marks
Armor Seals
Magic Resist Per Level Glyphs
Attack Damage Quintessences

Is there a more efficient way?

3 AD Marks
6 Armor Pen Marks
3 AD Quints
MR/lvl Glyphs
Armor Seals.

(Edited)

MS quints is where its at

No. Not for Jarvan.

150 games played with J4 checking in...

Most efficient IMO is:

3 AD Marks
6 ArP Marks
9 Armor Seals
9 MR/lvl Glyphs
3 AD Quints

Gives 10 ArPen (true damage to creeps in jungle), 10 AD for stronger hits, 11 Armor which stacks very nicely with his E passive (~73 w/Standard out if you start Cloth+5), and MR that levels with AP carries power. I've tried AS with a Vamp Scepter, but it's a tad slower than ArPen runes. You really want that ArPen at low levels of jungling because it takes fewer hits to kill creeps.

Actually, this is what I meant to post... 3 AD Quints, not ARMOR Pen Quints. :X
