Observation, the adc is no longer the "dominant" or "alpha" in lane anymore
Maybe im incorrect, but it just feels like the support dominates the adc right now? Like, a brand support is way scarier than the jinx adc. Even Janna is dominant if she maxes W instead of her shield.
I'm not suggesting anything by this, i just wanted to make an observation.
Her most popular item set is rushing these which cost 10,200 (her second most popular build does deathcap instead of zhonyas so it would be a few hundred more)

which cost 7100 gold, and those 3 items are her 5 most bough sets just in various order.
With
and
with
then that's completely false.
