So we all know Support is the least desirable role, but from my point of view, it is better to have a bad adc or a bad midlane than having a bad support, from wich you map vision, heals, shields depend on.
At first, i've tried to play carries (ADC or Toplane) to get my secondary account out of silver, but without too much luck. No matter how hard i was trying, the support role was always filled by someone that had no clue what vision or help is ( some supports haven't even bought the ward item) .
Apparently, most of players tend to preffer the "dominant" roles, as they watch montages, LCS and whatnot, making the support role a big no-no.
TL;DR I am a diamond player that cannot get out of silver via carry role, but did it in 6 hours with my main role.
