Why do people think LeBlanc is a relatively easy champion to play?

What are your thoughts?

There are so many champions that can counter her. Ahri, Cassiopeia, Katarina (late game especially for Kata), Annie (just needs to press R) (I would say Veigar because as soon as he stuns you he can kill you within seconds, but I just then stay really vigilant of his stun and then he's redundant.) (I would also say Yasuo but I've found a way to counter him as well.)

Cannot aggressively push or even push if they have a competent jungler. Can be very competent at clearing minion waves, but you can't move past that then. Must dominate mid lane early game without CD, which means that pushing is really difficult because of potential ganks. To push here you need your jungler's help, and if the jungler is too busy helping others or cannot support effectively...

Burst irrelevant to full-on tanky champs.

Screw up a combo and you're screwed. (Not many set combos; very situational which of her abilities to use.)

Sometimes completely ineffective against a team in close quarters because you can't get close enough to apply damage.

E short range and a lot less effective in a team fight if you are forced to solo defend a turret; no way to poke without dying.
