Isn't Senna range a bit too high?

And by a bit I mean way too high.

600 at lv1 considering it also scales due to her passive? Like I get anywhere near the minions wave, she just pokes, like non stop. And it's not very light poke either. And she has a heal as well.

It's nothing like dealing with a Nami on instance.

It's a lot worse since she can match most supports early, but heavily outscale them later.
