Change vayne's W into magic damage and make it scale with ap

Change Veigar's R into physical damage and make it scale with AD.

Change Tristana's E into magic damage and make it scale with MR.

Change Kalista's E into magic damage and make it scale with AP.

Tl;dr gutting a champion's strongest power instead of making their weaknesses easier to exploit is bad balancing.

Vayne would just build like Teemo, then?

I thought her W always did more damage to squishes.

Or was that a rumor.

3shot?

Yep, pretty sure you're not thinking right

"HEY GUIZ, I THINK I KNOW HOW TO MAKE ULT BALANCED!!!! JUST CHANGE IT TO MAGIC DAMAGE SCALING WITH HER MOVEMENT SPEED AND REMOVE ITS CC!!!"
