I can only talk about champions i've played... Corki got nerfed too hard in his dps and burst with the increased CD per shot in his rockets and lower damage in his abilities. He would be picked more if he were not outclassed by Jinx, Lucian, Sivir, and Draven, all of whom have great early games to stomp Corki during laning phase, with little to no damage fall off in late game.

Skarner is crap tier. The rework nerfed him by changing his permaslow so that his ganks are even more unreliable than they already were, and like Corki he is outclassed by the competition. Lee Sin, Vi, Pantheon, and Elise all have great mobility, strong ganks and gank pressure (some can even pull off lvl 2 ganks, which skarner can never dream of performing), high early game damage, good to amazing dueling potential in the jungle, and overall utility.

Galio is a great niche pick, especially in mid lane. You can just laugh at Leblanc as you taunt her with your ult if she tries to dive you under tower.

Alistar is also a great niche pick in support. He counters supports with high CC or dive potential with his own CC. Leona's zenith blade or Thresh hook connect with your ADC? No prob, just pummel her away. His own CC is also amazing against champions who need to channel to do damage (Kat, Fiddle, Xerath, Velkoz, etc.). Not to mention that his potential 5-man knockups can carry team fights and synergize extremely well with Yasuo ult (if Yasuo gets past ban phase)
