^And costs a butt-tonne of mana

E first IS a plausable option in rare situations. Such as with a Soraka support and you need the CC (and she gives you mana to sustain it), or if you plan to do a lot of fighting in the jungle.

However there is another reason to max Q first over E and that is her ult. At level 7 you can use it twice when you ult for two stealth procs. And at level 9 you can use it 3 times.
