Solution to Nami ult + Windwall
Current behavior is that Nami's ult is blocked by windwall, even if it only clips a corner of it. This is reported to be intentional, but it looks really, really weird.
My solution would be to split Nami's ult up into multiple projectiles, say 4-6, each of which would get blocked independently by windwall-like abilities (e.g. Braum shield). This way the entire wave wouldn't vanish due to clipping a tiny corner of windwall, but at the same time it would make more sense. You could probably even avoid doing too much graphical work by making each of the mini-waves scaled clones of the current wave.
EDIT: Like this - https://realadventuresofbecomingme.files.wordpress.com/2015/11/wave-breaking-over-sea-wall.jpg This would allow him to block only part of the wave without making it look quite so ridiculous. And yes, it would probably mean that he could only block about half to 2/3rds of the wave at most, but I don't think that's a bad thing.
main) and this isn't truly intended as a nerf, because it honestly wouldn't cut off that much power. It's more that I think it would be a cool interaction that, at least from the outside, appears feasible as a mere script, rather than an engine change.
's ult be considered a "beam" and make windwall not block beams
