Support is my favorite role and in Blinds i only run into a very small amount of "DOUCHE ADC" players who think they can decide what i buy and what i do.
To be a good support...
You have to play like you were that ADC. if you feel the lane should be pushing at the moment then you can help "Speed up" the ADC by taking some health off of minions so they can kill them faster and the lane will push.
Thats your decision to help as support. if the ADC doesnt like it... too bad. its not just his lane and like him you want to win the lane. If he sees you speeding up he can ask you to slow down or speed up if he feels so inclined but in my experience.. only like 1 out of 30 ADC will even say anything when you are attacking minions to help push.
I have ran into ADC players who literally fed the enemy team because i was bruising minions. and he said every time i auto attacked a minion he would feed. if you run into this type of ADC.. PLEASE keep attacking the minions and let them feed so you can report them for feeding.
Because while taking it upon yourself to help the adc push is not against the rules and it not a reportable offense.. feeding is. and if you are an ADC like this.. i hope your account gets perma-banned.
I feel like a lot of people who say "i hate support support sucks" are those same people who dodge when they dont get their lane becuase they were "born to carry this game" because they are "gods gift to league of legends"
if you cant play multiple roles.. then please uninstall. some lanes may not be to your taste or liking but when that happens try a new champion., learn something new. dont throw a tantrum cause you didnt get YAS MID like this guy did with me the other day. 37 minutes he complained about it. and he still got an S+ top lane YAS.. but he is still a noob because he wants to cry about not getting his preferred lane.
dont be that guy
