I’m not sure whether this would significantly contribute to lag, but I’d like to suggest/request a thin circle around each active player “spot ID” to signify the “area their squad occupies”.
This is just an approximation, or circle of probability, based on the random dispersion of the squad members. The circle would shrink as the squad members die until such time as there is only the player dot left.
This would help in coordination of attack and Defence.
In Attack, I can see roughly the weight of numbers pushing to an objective, as well as gauging the convergence across the frontage.
In Defence, similarly I can see the gaps in the line and with the shrinking circles estimate where reinforcements need to go.
Some of the more experienced players probably do similar estimates already, but a visual representation of the relative strength of friendly forces on a given point of the map could mean the difference whether to reinforce or go for a flank maneouvre.
