Most issues from what I've seen is these players that need to brag to place themselves in some sort of pedastal for playing this game online. And when they get bopped in a legitimate way, they complain. Some of those players just make a character look good but they don't exactly shine when they get overwhelmed by something extraordinary.
And when the lag kicks in, the legitimate way has stopped progressing and their feeble minds will go "I need this lag to win, don't care anymore. I'll do whatever I can to make myself look good."
The thing is, once lag comes in, there is no possible way to play legitimately anymore. It's not your fight anymore, it's the lag's fight. And besides, most people online just mash anyways, because they know that it will work, or they don't know it will work and believe it's "skill". The only pedestal they can put themselves is one in front of their friends who don't play. Anyone else will see through the BS.
