The roll is called support...
not super mega secret op, death dealing, hog squealing, rip snorting, belly aching badass. If you run screaming head first into a 2v5 the support can't get a quadra so you can 1v1 your nemesis. Stop blaming your supports adcs.
That being said obviously a bad support is a bad support, buuuuuut don't waste the time on the blame. Just play.
edit: wut is spelling
