Why do supports have to feel so handicapped?
I understand that the current meta often calls for a duo lane with a Carry and a Support--the support often having CC and steroids for their carry.
My question is why does the Support role carry weight as the "handicapped role" or "underpowered." They're already at the lowest gold income, why do supports like Sona, Nami, and Janna have poor scalings on their heals, shields, and CC spells?
I believe that all the mage, poke, and utility supports should unite! Just because their build paths may not support the scalings, they shouldn't scale like crap, Riot.
On the other hand, disablers like Thresh, Blitzcrank and Alistar are in a good spot as frontline controllers, but their tankiness scalings really should be looked at.
I never understood this concept in League of Legends, throwing supports under the bus: they're champions like any other. The title "Support" seems more like an impairment than a rank at the moment, and I think they need to be looked at from a broader view.

for an example.
(annie lulu and lux were left out of your post but I feel they still fit for this part) Their ap ratios are formidable in solo lanes.
. If utility ACTUALLY scaled nicely, maybe it would be, and it would make each supports more unique in how they support their team.
