Can we get some actual counterplay to LeBlanc's level 6/7 all in?
Q + W + R + Ignite without landing her E actually kills almost every AP carry in the game from 100% health. You might survive it with 10-15% health if you rush an early mantle, but if she lands her E, you're dead.
With a 2-3 kill advantage, the Ignite becomes optional. Even if you rush more MR, the Q + W + R is still going to leave you below 50% health, more likely around 30%, making it impossible for you to stay in lane.
This is a really unacceptable level of damage for an unavoidable combo that can be pulled off at ~900 range.
