Bring back elder lizard passive on warrior.

+45 AD +10% CDR UNIQUE Passive (Incinerate): Dealing physical damage deals 10+(0.2 AD) true damage over 3 seconds.
Note: this is weaker than Lizard unless you have over 200 AD. good luck with that as a jungler.
This allows Warrior junglers to scale a bit while introducing a known passive that has not been shown to be problematic.

all hit 200 AD in jungle.
But I agree, Warrior is super weak.
