Opinion: Supports should take blue wards; junglers get sweeper
This isn't the meta, and it doesn't seem to be what people believe is good, but I'm pitching it because I'd like to see where I'm wrong. I'm basing this on the outlandish lack of vision in most of my games, and the lingering cultural imperative that the support is the warder (exacerbated by the fact that Riot made their icon...a ward).
With Ruby SS, the blue ward is going to be up for use a lot more often. Furthermore, it's existing vision someone has to physically remove. So us warding I would guess leaves the map lit up more consistently than our traditional wards, and relying on others to ward period.
Furthermore, we tend to be squishy. The nerf to ZZ'rot only hurts tank support more than it had already. So your support is likely to be a mage, and it's better to give them ward range, and let the jungler sweep, given that they're often melee, rarely utility, and tankier in general.
Thoughts?
