How is LeBlanc's design even remotely close to being healthy?
Stand 1300 units away. Dash in, do 2.5 AP burst and then disappear before anyone can retaliate repeat for half damage after 6 seconds then repeat for full damage after 9 more seconds
(And if anyone dares to split off even a little bit, you can unload your full combo for 3.6 AP burst, which also roots for up to 3 seconds. and is also back up in full in 15 seconds. Alternatively you're free to do this on the enemy melees during team fights.)
