Assisting is hard work, but not only assisting heroes can assist. As long as it is a hero whose blood is thicker than water. You can't kill Batman yourself, you can only watch the shooter kill Batman. If the opponent's hero comes to hit you, the assistant can only let the shooter run over and hit himself, helping the shooter kill two people of the other side. That's about it.

Shooters have little blood, and they are all long-range attacks, and they want to kill soldiers themselves. It's okay. Two people across the street. If the two people across the street want to hit you two, you run and let the assistant carry it. Make a phone call. Shooters are generally explosive, and playing in the back can kill people with a few moves. When shooters fight together, they are in the back row.

Soldiers can sometimes be assistants, and more than half of them have more blood. It's all short-range. The assistant is two men, and the soldier is in the front row. He should rush ahead and resist the harm of five people. I have to protect the back row, resist myself and let the shooter output.
