Riot be like

Let's nerf electrocute it's too op does too much damage and requires no skills (requires 3 abilities or aa to hit to proc)

Let's nef predator its too op running fast at the enemy and doing damage on first hit is too much

Let's nerf dark harvest because junglers stay in the jungle too much (proceed to nerf jungle xp and planning more jungle nerf)

Riot - we don't know why domination tree is weak or why no1 wants to play jungle anymore (filling usually gets me jungle now a days)
