I find ( and I might be very wrong for it) but that since BF3/4 people walked away from the "tactical" point of view... so many times I try to get my team to see that once we have a few flags and KEEEEEEP them we win. Problem is the new games are so fast pace and "visually involving" that people forget to actually look where they are going and just follow "the rabbit" or next kill.
I believe I'm not that good a shot and I tend to die a whole fucking lot but that give me 1 advantage, I get to spawn a lot too. I most of the time try and go for the hard spawn, a flag that's in the process of being captured or I know a lot of enemies are moving towards, if only to try and slow them so we might keep the flag once moer "capable" people arrive. For me the minimap and even the big one are used all the time to see what the enemy is moving towards, blinking flags means enemies present even if not spotted by UAV or commander so those are first prio. Second is movement, what direction was a soldier/squad moving towards when I got shot or killed, even though I'm most likely to die again I'll go there to frustrate them or even cancel their action...
I know this all sounds valiant but it sucks lmao. I die a lot and scream at my team in chat to try and get them involved too but most of the times its in vain...
But to get back to the second screen from Sweney I would definitely use it as you get a much easier "tactical overview" to motivate your own and teams movement.
