I've just come out of a terrible streak of terrible games where one side simply camped en-masse the other side's generators while people simply flew in, grabbed the flag and flew away. Without base defenses up classes like pathfinders don't have too much of a hard time simply going around in circles from flagpole to flagpole I imagine.
Since you can pick what team to be on and everybody tried to be on that one same side, we ended up taking 17 flags in a row across four different maps before I decided to spend my time otherwise.
What ended up happening is simply invisible dudes using sticky explosives around the generator. Technicians' sentries won't target them, technician's SMGs are no match for their explosion spam and even when I switched to more powerful classes such as Jaggernaut I had an extremely hard time with them camping bastards.
How can I cleanse my generator out of those pesky people? or am I fighting the wrong fight? I was assuming my teammates would bother with other stuff such as defending the flag or attempting to capture theirs but I guess that's not what was going on.
