Playing a support is very easy if you follow certain steps, dont take your carries farm, or purposely try to get kills, this will in fact hurt your team very bad seeing as how soraka doesnt really do alot of damage. The more you let your team get kills and farm, the better for you in the end. If you blaming your team when your a 5/0/1 soraka, you should actually just blame yourself since you failed as a support.
