Silly OP, don't you know how riot reworks go? First, they take an underplayed champ. Then they dumpster everything about the champ that appealed to fans of said champ. THEN they slap on new shiny abilities and skills that no one wanted to make them appeal to more people. THEN the champ becomes flavor of the month, usually due to being hideously OP and gets spammed every game because of the new abilities, so they have to nerf them into the ground to compensate.
End result. A champion who is still underplayed, but now no longer appeals to the players who played them in the first place when they weren't so great. This will be the SECOND time they've done it to Skarner, and Cass still hasn't recovered from her little rework. It'll happen to the rest too, just give it time.
