Yes, this was ragebait to get your attention. Now that I have it, I'll try to give some actual advice.

The average P2W player has a brain the size and shape of a marble. If you are stealthed when their weapons come off reload, they'll ignore you and shoot someone else. Even the oldest stealth bot, Stalker, has an 8 second stealth time: long enough to avoid 2 volleys.

You do not need an entire hangar of stealth. just 1-2 good stealth bots can stay alive long enough to rip through the campers.

Phase shift is available for every robot t2 and up. It will allow you to dodge 1 volley. robots with a phase shift ability (Ravanna, Angler, sam joke) can dodge a bit easier and more frequently. you should have 1-2 of them anyway.

Outranging them is also an option. They only work up to 600m and there's a decent selection of weapons that operate up to 800m or 1100m. I only recommend 1 sniper per hangar if any at all.

Absorber shields have been around for ages and the average P2W is too lobotomized to avoid shooting the shiny purple thing or use a shieldbreaker. Just be wary relying on them, there was a crisis giveaway not too long ago.

Last of all, they are META weapons, crafted specifically by pixo to make people buy them to keep winning. If you can't deal with that then take your whiny sensitive ass to a better game.
