A proposed Rammus buff

like many tanky junglers has a hard time clearing jungle while the current popular jungle champs. So I am proposing a buff that would help his jungle clear. So I looked at his W. Rammus goes into a defensive formation for 6 seconds, increasing his Armor and Magic Resist by 40/60/80/100/120 and returning 15/25/35/45/55 (+10% Armor) magic damage to attackers.This ability gains damage equal to 10% of Armor.Activating Powerball will remove this effect after 1 second. This is his current W. I am suggesting that instead of 10% armor magic damage to all we change it to 10% armor magic damage to chamions. 15 or 20% armor magic to jungle monsters.
