Not to mention Nami poke can bounce to minions if I'm not mistaken
You are mistaken, I suggest you actually research champions before discussing them:
http://leagueoflegends.wikia.com/wiki/Nami
Nami's W is literally all 3 of Sona's basic abilities in a single spell-cast. Then Nami still has 2 more spells after that. In just a single activation of her W, Nami: A; does more damage than Sona, but at almost 200 extra units of range, B; returns a bounce to heal herself for almost double or more of what Sona could and C; triggers Nami's passive which is like Sona's E, but with a higher base.
There's a reason Nami's been considered a superior copy of Sona, going as far back as patch 3.14.
Hell, we haven't even gotten to discussing Bard who is a superior copy of both of these.
