I've seen this sort of thing myself.
In Garden or Graveyard Ops I would occasionally find a player far away from the Garden or Graveyard we were supposed to protect and their character would be one with a good jumping ability and they'd be at the far end of the map up in or on some extremely difficult to reach place sitting out all 10 rounds of play and possibly even the evacuation phase just to get credit for being present in the game because of a Quest requirement.
In Multiplayer I think everyone has seem that one Player on the team sitting idle, which is to be expected as sometimes Real Life demands your attention, but what is worse than that is the fool dong nothing but spinning in place or shooting the wall, or team mates, or otherwise not playing to the objective.
In Cats vs Dinos yesterday I wound up on a team with at least one Player who simply either sat out play entirely until an opponent noticed him and took him out of play or who just mashed their face up against a chunk of rock and wiggled back and forth occasionally waiting for the timer to run out.
The former two situations I don't encounter too often because outside of Ops when it's just a maximum of the four of you it's not really all that easy to keep track of what teammates are doing, but in Cats vs Dinos because you get forced into Spectator Mode after you're vanquished it's easy to spot the people who are simply handicapping their team by taking up a slot without participating.
