I did misunderstand your point to a degree so for that I can say sorry. I still believe we will disagree.
What it brings to the game is a competitive spirit that without would diminish the intensity of PvP. Psychological warfare plays a big part in pvp, that's why it's so widespread. There's more than one way to defeat an opponent. Now that's a somewhat serious point to be made for something that for the most part is childish banter. If someone really did cross the line, whether it be spamming profanity like an idiot, constant threats to someone's life, or (and this is what I consider the most unacceptable form) revealing someone's personal identity, I would be more than happy to report said people.
I feel like waving the ban stick over some "bad words" is a ridiculous over reaction unless very specific criteria are met.
Personally I enjoy watching some freak out in broadcast against me, it let's me know not only am I the better player, but I have truly impacted this persons emotions to the point they no longer have any option but to insult me in some way. This is hilarious to me. I've said before though I have a sick sense of humour. I'll even go for as to admit this is a stupid thing to enjoy but none the less, I enjoy it. ( far more than I probably should )
There has, and always will be a massive difference between those who love pvp and those that love pve. One thing is for certain though, both groups have idiots that ruin the experience for others. Both have ego driven players that cannot see the humour in how serious they take a game... The big issue here is that when pvp players are idiots an entire zone filled with large amounts of people, if there is an idiot in PvE chances are only 8 or so people will see it. Also it's very difficult to achieve such an adrenaline rush in PvE so the odds of someone acting so childish decreases drastically.
I guess my ultimate point here is, I respect your view, but I just don't see a way of removing trash talk from the game without harming the community. I'd much rather have people say what they want and chance them not being punished rather than have people not say anything afraid of being banned.
Now with all that out in the open I can't see this problem being near as bad as it was. Many of the players of the past have grown up. Not only that I can't see people waiting around this long just to talk s**t to someone
that's like South Park levels of satire.
