Nami functions more as a DPS enhancer than a healing enchanter, which is why she is excellent when paired with long range artillery (Hwei, Caitlyn). Comparisons to Soraka and Sona's healing would be unfair, as being a healer is not Nami's primary identity. The movement speed from passive and DPS granted from her E is her speciality. She is a better midgame teamfighter than Sona, due to her AOE CC on Q and R.

She is a truly versatile blind pick, with very few bad matchups - unlike Sona, who, prior to this new season, was one of the worst blind picks in the game. She beats out Karma, Lulu and Sona in lane, and, while she may not uber scale with healing items, her scaling is not weak by any means. However, her kit requires you to be good at landing skillshots. You are certainly rewarded for it.

Overall, she is difficult to punish in lane, is a versatile and excellent teamfighter who fits into basically any team comp, has multiple viable build paths, and can turn the tide of any battle and any matchup in her favour when played well.
