You have mistaken. Harass support is real support, but I give my story - why I ceased to play healwr/tank support.
I did try to play support like dps bullies wanted,but I got really frustrated as my win or loss was not in my hands, but usually totally incompetent adc did caus e loss,or rare ecperience of decent adc who treat support as equal. I tried harass dipports, and suddenly I could make the difference. I could defend tower when, not if, adc de facto suicided in desperate attempt to take kill.
I did learn to play during season 1. I learn support is mobile role like jungle going where needed. I reverted to that way, and I have plenty of comebacks. Support roöe shoild be put outside lanes, but adc players do not want to lise their scapegoat when lane is lost.
