Theorycrafting for new mechanic: Imagine if you can equip 2 keystones at the same time.

Just think about these possibilities:

• Ferocity Tree:
• Fervor + Warlord's = Heal that scales with AD from Fervor.
• Fervor + Deathfire = DoT that scales with AD from Fervor.
• Warlord's + Deathfire = build more AD to amplify your DoT from Deathfire and heal from Warlord's.
• Cunning Tree:
• Stormraider's + Thunderlord's = Free burst damage and movement speed.
• Thunderlord's + Windspeaker's = Have burst and utility at the same time.
• Resolve Tree:
• Grasp + CotC = Get both a shield and heal when you auto and use a CC skill.
• CotC + Stoneborn = Apply earthen rune debuff and get a shield at the same time.
• Grasp + Stoneborn = Heal off from your own auto's and apply a heal for your teammate if you hit any CC on that target.

I know I know; this is gonna be very broken on certain champs. But let's see what the results are if you can use 2 keystones at the same time and theory-craft on how effective that combination of keystones can be.
