Malzahar Passive Change

Malazahar's Voidlings are strong. Very strong. They are such a hidden power in-lane that you probably won't notice how much of his damage they are early on. However, they become drastically less powerful late game. Why? Because they have a limited duration, are single target, their damage scale off of Bonus AD (what?), and are summoned based on spell casts and lets face it, it's not worth managing your spells late game just to get the Voidling. So I recommend a change to better put the Voidling into Malazhar's kit.

Passive- Summon Voidling

• Normal attack damage decreased to 19 (+4 per level)
• Added 0.15/0.2/0.25 AP ratio to Voidling Basic attacks scaling up at Level 1/8/16
• Voidlings duration removed
• Voidlings now have a max amount on the fields at once (1/2/3 at Levels 1/6/11)
• Armor changed to 14 (+1 per level) from 30 at all levels
• Magic Resist changed to 28 (+2 per level) from 50 at all levels
• Grow delay increased to 10 seconds from 7 seconds
• Frenzy delay increased to 20 seconds from 14 seconds
• Frenzy now adds a cleave to Voidling basic attacks once Malzahar reaches Level 11, dealing 50% damage to enemies around their target

Adding more Voidlings and removing the duration would make them much more noticeable late game. The cleave would also make Malzahar viable in teamfights since his impact on a teamfight ends after his first combo. Thoughts?
