Hi there i was just asking what runes should i build on Shaco i wanted to get crit dmg quints but im not sure if someone could help me i would be thankfull ;)
^That's what I'd use. AD quints might be okay since his E scales off bonus AD but deals magic damage. I like the AS/Arpen setup on most physical damage junglers though.
As long as marks and quints are Attack Speed, Armor Pen, or Flat AD you should be fine. The problem with critical damage runes is not just the fact that in general they are not very strong. Also, the fact that it scales with Deceive is not enough reasoning to do it. You would get a lot more reliable damage if you stuck with flat armor pen, attack speed, or flat attack damage. If you really want to have critical damage in game you can buy an Infinity Edge assuming you're doing well.
2x Greater Mark of Armor Penetration
9x Greater Seal of Armor
9x Greater Glyph of Scaling Magic Resist
3x Greater Quintessence of Armor Penetration

Crit damage runes are awful.
it depends on how you play him .
