I'm sorry lazy? You're kidding right? There's maybe 2 extra thumb movements and increased wait time of maybe 10 minutes at the most. Hell you don't even have to move to do Lfg. There's little to no difference in effort and time between matchmaking and Lfg to call it "lazy". Now I'm sure there are people out there that won't use Lfg simply because it takes such little more effort but I'd say they are the minority of the community on this topic. And you can find exactly what you mentioned above in Lfg. When it comes down to it you don't know the people you're playing with in both methods of finding a group. People found both ways can be AFK and can have no mics. Personally I like both methods and wouldn't hurt to see it made optional.
