While playing matches I find myself always closed in by mercenaries, specifically Rhinos and Bushwhackers. I try to push to the objective just to find myself being killed relatively quick by the turrets or miniguns. I see my teammates leave as they do not want to stay in a game where they will just be constantly killed. That leaves our team at a 3v8 or a 4v8 because of how frustrating it is to play. Is there a strategic way to push into these objectives while still pushing out the enemies?
How do I counter spawn camping?
You should flank if you can, turrets won’t shoot you if you approach from behind.
Using an engineer and suiciding to repair an objective can help, since when the objective is complete the spawns will change.
If it’s not under a roof, fire support classes are great. They’re made to take out entrenched enemies.
My best advice: Nader (or maybe fragger will do also)
Spawn campers are generally packed tightly and stay on the same spot untill they die. I use my nader to shoot some nades around corners or maybe even suicidely run into them and blow myself up.
It does not give me a killer score, but eventually breaks up the campingspots.
I finished 3 games earlier 1v5 because my team mates left due to spawn raping lol…
I tried my hardest to get out but was lucky to kill 2 of them 
Why is it allowed so easily? This is the only thing I’ve heard from friends as a negative.
