If supports are so easy, then try supporting someone who is OBVIOUSLY not an ADC main sometime.
Or just a really bad adc.
Ive actually had a first time draven first time adc before.....
There is a lot of things that go into being in a duo lane that make it difficult. Often times its one of the higher stressed lanes simply because
A) your most likely to have a 4-5 man gank before minute 10.
B) if you die once or twice, there is always someone there who is like "wtf, why did you do that?" "Report this adc/support" etc.
C) you have to actually find some kind of common ground between eachother's aggressiveness levels, and you need to know 2x as many champion strengths and weaknesses just for early game.
D) it is a highly pressured part of the map. The only lane that sees ANY kind of similarity is mid lane. This is only because it is fairly close to Dragon pit as well, and its an easy roam for supports to go mid.
This is just part of the issues with your mentality there.
There is no "easiest role". If you are new to that role you will get stomped by a main of that role 9 times out of 10. Thats because they have the knowledge of that role and the various strengths and weaknesses of that role.
There also is no "circle jerking". There is people telling you things that you obviously overlooked. So get over yourself with your highly held self opinion.
I repeat. There is no "easiest role". There may be an easier for you...... but there is no blanket easiest role.
