To the people that pick dps when there’s already theee of them, what is your thought process dawg

When we have 3 dps the amount of people that pick dps even though we have enough/ maybe more than enough. What is your thought process? What are you thinking? Im so damn tired of having to play support every single time just for 4 dps dolphin diving into enemy lines cus they think they're invincible just cus they have ONE support one their team. "hmmmm we have three dps and one support and one tank, what do we neeeeed... ah! Of course ! My negative kd Spider-Man will help the team tremendously, Im sure that support will be fine alone" NO I WONT BE RAAAAAGH
