It's boring and no one listens to orders because ever round is exactly the same for both sides. For marines it's run into the caves and shoot shit. EVERY round. The only way to win is to shoot the xenos. Forever. Doesn't matter the map.
For xenos this is fine. they work well together as a team. they are "okay" right now.
But adding more tools isnt going to fix the problem for marines. Command is irrelevant. It wont matter how many fancy arrows, lines, whatever. If the only way to win is to kill the xenos.. then people are going to run into the caves; period. 95% of the map is irrelevant. Marines play entire rounds without command; the xenos cant play for 5minutes without a queen.
The solution is that you need to create more ways for Marines to Win.
Command is only useful if it can make decisions; and the current decisions it has is to push forever, or evac. And those are the only things marines look for, or listen to.
You need more ways that marines can win the game.
For example, if the marines could instead hold engineering and charge a particle bomb.. command could choose between eliminating the hive, or utilizing the bomb. Briefing would instantly become more interesting, and orders matter more. No longer are we pushing to hydro. Squads would have to pay attention.
Throw in a few more win conditions like developing a virus bomb in research using captured xenos (I dont know whatever we can put our heads together on more win conditions). Suddenly command has to make choices between which path to victory (or abandoning some) to take. You were trying to charge a bomb in engineering then ob'ed engineering? Better change tactics.
You need to give marines a reason to interact with the map. You need to give them a reason to hold points. I mean it doesn't even make sense lorewise. The ONLY option command has is to send endless waves of marines into a scary dark cave full of xenos until one side wins? Fuck that..
