There are bad supports as well as bad ADCs.
Treat your support horrible enough I've seen many times in videos A support abandoning botlane and helping the toplaner get fed because the ADC is being a toxic whiner baby. I have also seen my fair share of toxic supports.
you get behind in cs, or you die and feed the team, the SUPP HAS to know this danger and adapt to it,
This is where you lose it in the post for me. Not just the support has to adapt but the ADC has to adapt too. You have to realize as a 0/2 ADC that you cant 1v1 ANYONE! even the enemy support may be dangerous to go in. And if you suck, and get caught out there's only so much a support can do..
Same with support.. if you get caught as a support your adc probably has little to no CC to be able to help you..
#All in short Support and ADC neither of them are better than the other.
You need both of them working correctly to win a botlane. Sometimes even when you have good synergy theres a chance you could face a botlane that is better than you and still lose.
The point is how you come back from losing.. An ADC who's underfed and under farmed won't do much for team fights.. You need to find some way to farm safely. Supports should always follow around the carry. But the carry isn't always the ADC, sometimes it's the top and midlaner. Perhaps while the ADC is off farming to catch up, the support can follow any of the fed teamates and help them pick up a few more kills to really get them snowballing.
As supports were not here to just support the ADC, we support the team..
I main ADC and Support and I know if I do bad and my support goes off to help other people I know it's my job to find a way to catch back up and if I have to farm like a madman for 10 minutes to have 175 CS by 20 minutes.. By gosh I will try.. because unless you find a way to get back in the game you are dead weight to the team if you only have 1 item and boots 25 minutes in..
