You are right on all you said, but most of these problems you mentioned can be solved if they high the bounty prices.

There is a kind of anti-boost system, but honestly I dont know if it works.

In order for Bounty points to work, there needs to be a anti-boost system that is guaranteed to work... And im sure it won't work because many people cheat around the boost system often...

Also you can easily boost kills if you go to the towers and just kill all those who enter by the door

You are right, but also I dont know how effective is the anti-boost system that is being used already.

That would be just PKing.
Boosting is more like PKing an AFK player to get a lot of kills from it.

Ik what Boosting is but what i meant by boosting at the gang towers is like when the players come in and either in front of them is a bear trap or explosive along with rapid gun fire at them. They can repeat the same thing over and over again. I got 20 kills in a row because of that
