Just had a couple runs against bots, I think he benefits way more from Trinity Force than either BT or IE. His main source of damage are his mimicked abilities, the cooldowns are insanely low and they HIT DAMN HARD. With a full build, Q was hitting for 600 damage, and E for around 480. I went with:
Merc Treads Brutalizer -> Ghostblade Bloodthirster Maw of Malmorthius Trinity Force Didnt even build a 6th item (Last Whisper for the win I guess)
The Tri-Force is so imba on him, his E cooldown is like 3 seconds, and his Q is around 5 with Ghostblade's 15% CDR.
His abilities don't really make use of TF's stats. The 15% critical, and 30% attack speed only apply to AA, right?
That leaves his abilities scaling off TF's 30 AD vs BT/IE (60/80 AD). Chances are you're not building Zed as a right clicker, so I don't see the use in this item, but I could be wrong.
Am I wrong in my reasoning here?
His passive also makes AA deal bonus damage to enemies with low health, so you do need to AA as well, but yeah, his main strength is the low CDs and the insane scaling of his Q. Its ridiculous, it's a 600 physical damage fast skillshot (900 if you hit the mimicked shuriken as well) with 5 seconds reuse (with ghostblade) on a highly mobile champ.
