I think is not necessary, we need to practice as a team, using binds and when a partner is frozen help them with binds, like: bh, ra, rl, yl, hall yl, q, etc... Follow team mates, be in a group, respawn and inmediatly join with a partner with the Team Overlay, follow the mate dont left him behind, if i Use Item first u follow no matter what and things like that, do not jump from one room to another and left behind your mate, thousend of things.
We need to practice, understanding us between each other and have a good strategy, that is all.
