Shen Question
So I've played Shen since his 2010 release and I've always adapted to improve on building Shen to fulfill different roles. One thing I've noticed is a lot of builds have him with Attack Damage or Attack Speed marks/quints. I've checked and retested time and time again but overall Shen does more magic dmg, so why would builds (rune and mastery wise) building AD/AS? Yes it helps farm potential but wouldn't it seem MPen would be a better option for any role (tank,fighter, even support)
