Magic Pen Marks on WW for Late game?

[quote=JunSupport]In one of stonewall's videos, it's said to take magic pen marks for later game. Reasons: His Q, and Madred's magic damage. However, auto attack damage is always > madred's damage(unless attacking some ridiculous 5k hp champion); madred's is just good for ADDING damage to your AD to make attacks effective, and most warwicks tend to build AD anyway. So I think Armor Pen marks would be superior when it comes to both early and late-game. Magic Pen or Armor Pen, guys?[/quote]

[quote=Jet]you don't get ad items on warwick (aside from madreds/wriggles), and mpen helps his hungering strike + the madreds[/quote]

[quote=Adonikam]Neither I think AS is better for junglers[/quote]

[quote=SinDelta]You honestly don't rely on your Q that much late game, just your right clicks and ult when ganking. Yeah it gives you a slightly better heal with the MagPen and slightly better madreds bloodrazor proc, i just feel armor pen and atk spd is the way to go for late game and early game for that matter[/quote]

[quote=DEWO]Just get Sorc boots. If you need more, you can get Malady instead of Wits/Stark as a 2nd AS item. Nothing more is needed.[/quote]
