This is a great game don't get me wrong, but the community is full of people that obviously had some trouble during their education.
Worse is when these people join the game and their bandwidth footprint so large that the whole server acts like Donald Trump has just sat on Tripwire's only working router.
Due to the plague that is Perk Training Servers, you often see players that have prestiged 5 times, yet still play like easy bots on Unreal Tournament.

Don't forget to buy the DLC, so tripwire can afford to host dedicated servers that can handle more than just 2 word documents at a time.
