AS a main assault player, I know that I am not going down any time soon.
Unless I KNOW that I will go down with 100% certainty if I do not use my shield, I will not use it.
Otherwise I have support supporting me, medic heals, trapper cc, adn my own power of dodging in order to stay up.
Whenever you target me, I cry tears of joy because of all the damage I am doing to you by getting all those glorious headshots at minimal risk.
not a good idea to focus assault unless support or medic is down.
