In just about almost 15 years of MMO forum posting, I can say honestly that this is on par with how it usually is. I would say actually that this is just a tad better.
You may be wondering why. Usually MMOs get the bright idea to let certain volunteer players help co-manage the forum, which inevitably leads to those said players going on power trips and banning anyone who disagrees with them. Its always that + the one player who seemingly always responds to every single post defending the company no matter how bad the situation-so much so, that you often find yourself wondering if the person even plays the game, because they truly seem to just lurk the forum the entire day every single day.

Both of these scenarios I don't see here, so that's quite nice.
As for the rest though yah, that's normal. It's like that everywhere though really. Anywhere that isnt real life, because we all know how IRL arguments go. They start and end pretty fast-usually with one going down town and the other in an ambulance. This is why we take to the internet instead. Much cheaper/no need for healthcare insurance.
