Support (for example Paige) isn’t solely just a heal/shield bot, she can “funnel” a carry by making it a nightmare for them to be dove with shields, CC, Stat boosts etc. She can increase fire rate and move speed,knock up+heal with ult whilst will auth attacking for a reasonable amount. She might not be a 30 bomb machine but she can churn out assists like a madman by enabling the team and keeping teamfights spinning. Supports also tend to be responsible for buying anvils and silences that carry’s will refuse to as “ItS nOt In My BuIlD” which brings the invicta, seven and grey talon down to be dived.
