+ can one shot nearly everything
+ high mobility
+ perfect escape from ganks with w+r
+ high one target + aoe dmg
+ can roam as hell

- hasn't that high sustain
- must get a early blue buff

can stand in the last part of the team to don't get catched, then clearly
one shot the enemy ad carry and ap carry with one good move!
but lb need someone who stands in the front line!

one shot EVERYONE, combo:
DFG, q,r,w, <-- fast kill combo
against tanks:
DFG, q,r,w,(wait a second and follow ) then q,e and the enemy is for sure dead!
*DFG is the Death fire grasp!

my runes are nearly the best runes you can have in the midlane as leblanc against EVERY enemy champ, because of armor magic res, magic pen and ability power!!!

at start farm with AA,
as lvl 6 when enemy isn't on lane or make hard push, then q on the canon minion then w+r
to get 7 creeps in 0,1 second and clear the wave.

stay on lane farming and harrase the enemy with q, w combo to dmg him hard.
with level 6 do the fast combo q,r,w,e to **** him with a oneshot
when enemy jungler come, just escape with w and r
when you used both then flash out timed

just go and play leblanc like a ****ing oneshot <3
when the enemy counters you then you wait for jungler and farm under tower
with lvl 6 start roam
and go for the win :)
