So cs...
The only thing that her camouflage will honestly be good for is mana sustain, avoiding harassment while not csing, roaming, and making the enemy think you are roaming.
While csing, you won't be camouflaged anyways, so don't worry about it.
But, you will want to drop into camouflage occasionally for the reasons mentioned above, or at the very least the enemy laner will anticipate that you will, so they are likely to buy and use a control ward.
It actually helps to make up for some of the difficulty she will have trying to farm due to her inferior range.
And again, I'm definitely not saying that this is a GOOD pick. I am just saying that it is possible and these are some of the advantages/disadvantages she has.
