They really don't help her that much at all. I really feel for her to be a viable support she needs her W mana cost lowered.

that is all.

edit: http://www.lolking.net/champions/nami#statistics

She is currently played less than 5 % of games, and has a terrible win rate ( currently 44% )

She needs something more than being able to cast her Q a few more times, she can't spam it as is because of her mana problems.

Nami has huge problems and needs some serious love not just some token 5 movement speed and an increase in the number of times she can cast Q early game only.

Nami is real fun and easy to play but a lot of people want to AP her and don't understand how AP nami can actually works. She faces the same problems as AP nid, Nami can only harass.

I think she needs a better E.

It's a tool that can really only be used to win an already won fight a little faster.

imho this is like saying Sona shud have lower mana costs so she can't spam (i build insane mana/5 + AP + CDR so i spam anyways). they have similar stats at lvl 1 except sona has less mana. so why does nami really need a buff. can't she just be played less aggressively?
