LV Koopa
Jester from Hell
He’s my go to Vanguard now. Once you get the hang of the animation cancel tech with his basic attack he becomes a real problem.
He won’t show up high on the stat board but if your team is even semi competent and will try to complete the objective while you keep the other team occupied Cap will play a big role in getting wins.
A competent Cap is one of the best possible teammates to have. They just occupy so much time and resources it makes the game easier.
You're right though, people look at the scoreboard instead of what's actually going on and don't realize how much damage he's doing.
Bonus points if the Cap is competent to use his ult to save the team instead of himself.
