Skarner is Dead

Before his rework, skarner was an underplayed and slightly underpowered champ. He has always had a very unique kit, made even more unique post-rework.

After his rework he was OP. And just like that he's gone again. Why?

Mercurial Scimitar. This item has been buffed and given life steal, a better build path, and is now a 3rd item on 90% of ADCs. This makes skarners kit unusable. If you're entire purpose is to reposition your enemy to somewhere more favorable for you.... But your target QSS your ult then you just took YOURSELF out of position for nothing.

Now you may say champs like zed have a similar problem.... True. But he was made for damage. For killing. Skarner doesn't really have that option. For zed, QSSing an ult means he has to try a bit harder to kill you because he doesn't have that guaranteed damage now. For Skarner, QSSing an ult means putting R on CD for no reason and likely walking into the enemy team to do so if you target the carry at the back.

I don't mind QSS lets get that straight. It's always been skarners counter. But now that its core on every ADC there's no chance to pick Skarner because you essentially just picked a 3 skill champ since your ult is useless every game now.

What is to be done about this? And similar cases i.e. Malzahar (I hate malz but it's only fair to mention him)
