What is wrong with the people who plays bte i couldnt even win one round in 20 tries in bte servers because everyone was getting even more mad than in normal servers trying to get weapons and kill everyone.

Unfortunately for an armed society to be a polite society, you have to make death kind of permanent. BTE adds whole new arsenals, and the boats are liberally filled with them. Fun for an arena shooter, but in public servers where a good 50% or more of the players are straight up griefers, it's asking for it.
