NERF Deathfire and Thunderlord Keystones RIOT

How can anyone fight people in this game when you have skill and are basically a ignite or smite in terms of damage. Plus look at the ratios on on them are they for ADs or Ap cause all I see is a riven dashing at me burning me for 65 damage over three sec on top of all her damage. Man I hope they nerf them or change them because who ever thought of these as a good idea and thought only mages will use them need to have their head looked at.
