Feet Are Strange: Nami should have a passive like Cass
Nami's current passive, Surging Tides makes her abilities increase the Movement Speed of allies caught in the effect. Cassiopeia's passive Serpentine Grace prohibits her from purchasing boots items, and increases her Movement Speed by levelling.
I think Nami should also have this affect in her passive: keeping the current Surging Tides effect and adding the "no boots" mechanic. This might make Cassiopeia's passive seem weak by comparison, if you just add a Cass passive to Nami's passive then it definitely creates unfairness. So I also think that Serpentine Grace should get something extra as well. Now, I'm not a Cass player, so I have no idea what would be fair- but I was thinking something along the lines of: "all damage dealt by Cassiopeia afflicts minor poison damage that damages enemies over time"
