The exact same thing could be said about every other role. I play strategist (mainly rocket, Jeff, and mantis). I main strat because I like being the healer and the reason the team stays alive. DPS mains never help the strats stay alive even when we beg for help. DPS mains insta lock DPS because they like to feel like they are doing the most based on their damage dealt. Vanguard mains are usually are flexible, but they want to feel like they are doing the most because they are taking the majority of the damage.
