Since Trinity got turned into an ADC Spellblade item-
And Iceborn is the Tank Spellblade item.
And Lichbane is the Mage Spellblade item.
Can we have a Fighter Spellblade item again?
Something like-
+
+
= 
Grants HP, Mana, CDR, AD, IAS, OnHit damage, AND
Unique Passive - Spellblade: After using an ability, your next basic attack deals bonus magic damage equal to (percentage) of your total attack damage and steals (percentage) of the target's movement speed for 2 seconds.
I think something like this would be FAR more attractive on champions like Irelia and Nasus than the current incarnation of Trinity is.
