I have found that the better you get at playing, the more everyone else seems like dweebs. In hindsite, I used to be an epic dweeb, I have changed (perhaps), the game has not. Perhaps some of your opinion is based off a shift in your perspective on game play. If you search deep enough I have some threads complimenting the HO, defending it even. Then again, that is all I knew. I despise the HO guys now.....
After a bit of mentoring and assistance from some of the game luminaries. I found learning ACM and actually trying to get on a guys six was a bit more fun and challenging than getting the quick easy kill. Until most guys figure this bit out, they will play as some of others perceive, to be dweebery.
The second piece to this is the personas people assume playing this game. If they were respectful 90% of the time, there would be little drama, BBs madness, or accusations of foul play. Since most can conceal their true identity and form, they inflate their egos based off of skill in a game. Again, a pit I have fallen into and climbed out of. Once I quit caring to be competetive, man this game got fun again.
So, I dont think the game has changed at all, just the more years you get playing it alters your perspective on other players.
