I love Nami but I feel the water element could be used aggressively as well. It's something Riot hasn't tried out yet. (And no I don't like Atlantean Syndra, she doesn't use waves of water to attack)
I don't think it'd be too many. So long as their visuals and gameplay are distinct enough, another merperson would be fine. Ivern and Maokai are good examples of this. They're both treants, but one is a tall and lanky pacifist druid while the other is a bulky and aggressive nature spirit. This naturally lends itself to gameplay differences (jungle enchanter vs. vanguard tank, etc.)
I think there is still room for a water elemental/water spirit.
But if we'll ever get another mermaid/-man-champ then its likley not going to be a water mage,because that would be indeed too similar.
I don't see it as problem in-game, but I do see it as a problem in lore. Nami is the hero of the Marai, and I think a new Marai champion would cheapen Nami's story.
No need for that when you have adc nami terrorizing the rift and Aram.
But it would be neat to see more of her kind. But as always, to hell with her we need more Morgana and Kayles first. :3
Why does it have to be a Marai ? Why not another tribe or species ?
My ideas :
Elegant but deadly Jellyfish lady who uses her lethal poison : https://i.pinimg.com/originals/1b/78/73/1b787353f9baf4d570245ad042819fc1.jpg

Nami is controling water btw, and if you build her full AP mid, she is aggressive, we just need other champion ideas from the seas...
We already have two trees.
@Riot gimme a sexy merman
we have about 10 void champs and 10 yordels, so why not a 2nd mermaid?
Unrelated but I thought of this when reading OP. Maybe Riot will pick it up
An ability where the water bender forms a water bubble around your head and if you cast an ability you lose HP (because you shouldn't open your mouth under water).
It is a new type of ability, where you'd have to follow your target with your mouse to keep the bubble going for 3-4s, (lasts 1s if you don't)
What about Fizz?
'too many merfolk' how would two be 'too many' when there's like 345838583 human champions and no one considers there's too many humans
I think adding a Void Cacaelia type character would be awesome, probably a midlaner of shorts, maybe even the guy that Nami had a run in with in the depths. Along with that, the ocean still has a few mysteries, so the introduction of another, yet evil Marai can allow Fizz and Nautilus lore to be updated
We have 2 bird Vastaya, loads of humans, like 10 yordles. I can't see an extra Marai being a problem. Make it a him, decked out in armour and make him a fighter. If anything it's kind of sad there isn't another because Nami is on her own, while everyone else has friends and enemies in lore.
