Why not give kled counter taunts to his... "Allies"
He hates everyone on the enemy team, his team, he hates himself to.
Would be a good nod to his lore of him talking shit back to his allies if they taunt or joke near him.
Back when kled was released and everyone was racing to instalock him in champion select if I was ever lanning against him or came across him i would intentionally taunt or joke near him to hear him rage back at me for the lols.

While we're at this subject he may as well counter taunt against taunt champions like Shen, Rammus and Galio.
