Thanks for the suggestions!
Well, as i said-choice of runes depends mostly on how good are you with last hitting and your personal choice cause both Armor and Magic penetration are really useful.
Armor pen marks help a lot early game, and help overall pushing power.
My personal preference are armor pen because Trample, no matter how awesome is, is not reliable farming help until you get at least 4 ranks in pulverize.
Also i must mention that choice of runes depends of what role will you play in a team.
If you are playing support you will take Greater Quintessence of Avarice instead of Fortitude because most people wont leave anything for you to farm.
Though i must say i totally agree with you Bmonet-magic penetration works really nice with Cow.
I tried build
And have to say-it does serious damage and works wonders versus squishy teams.
AOE pulverize hurts much more, and headbutt is legit finish move.
Though you will lack survivability but you should be able to carry your team early/mid game.
