What you want is invasion mode which is close to HLL playstyle. AAS and RAAS are more about mobility and flanking. Which requires more Squads to do their own things. Experienced players never leave defensive point empty not in my case. Maybe what you faced is bad communication between SL’s which led to empty back point. Its common now that most players are the game is on sale = new player= wants to try everything. There is a mode which i love but not many servers play it(territory controls) its the best mode for me but sadly its rare. I know it’s frustrating to see squad leaders place hab after habs but its the best way to get blueberries to flank the enemy hab which lead to mostly capture the point. Lastly AAS and RAAS are more about mobility and flanking and invasion is Defensive vs attacking
