: I didn't have a problem with a lot of quitting in Reach and I don't remember

Quitting a game is not even remotely a crime, so that's a bit of a nonsense analogy.

People are always going to drop out for a whole host of reasons beyond just losing.
They've gone to join a friend who's just signed on, their connection failed, a telephone call or someone at the door. An urgent bathroom break.

Whereas before people might have gone AFK, now they can leave without a significant impact on the game as they will be replaced pretty sharpish.

Whether or not you remember there being complaints in H3 or Reach rather depends on where you went. As the majority opinion of responders on this particular forum makes clear, there are strong detractors of the concept of drop-in/drop-out.

For the greater picture, I imagine that most of the time, most people just didn't care either way.
They were satisfied then and they are still satisfied now, so they don't complain.

I never really complained about the H3 at the time, though once I was introduced to Call of Duty 4 just over 3 months later, drop-in/drop-out seemed to make so much more sense for team games featuring so many players.
Especially when you only play with a couple of other people and use party chat or friends only communications. Everyone else on your team are just fillers for the numbers.
