I hate the idea of "hard to hit", its honestly so easy to hit with her strong slow. not to mention movement speed early on is horrendous.
So i could start boots/pots, right? well if you do this nami will legit just solo the other lane with no punishment while her adc farms because her damage and sustain is far too high, and if you start boot/pots your lane is lacking damage. She's a win/win champion. There really is no strong #counterplay to her.
You play a kill lane against her like Bliztcrank.
And no, her bubble isn't easy to hit because she has to sit there and auto attack you a good 2 times to proc the slow, and dont even get me started on trying to bubble a Lucian that saves his dash to juke it.
Her heal has high mana costs as well, i mean you must be at bronze 10 to have a Nami that solos the other lane alone by herself.
