1) the sound guy is hired specifically for working on sound; that's like saying the accountant should be focused on making a 3 course meal. he literally has nothing to do with the building mechanics.
2) it's not built around raiding, that's just one of the easiest elements in the game. and honestly, how much do you achieve by raiding at the moment? you can craft everything, resources are ample, and most bases are empty/abandoned while you "raid" (read hit the wall for 10 minutes, woot i iz a rayder boss!!!). it's more than pointless, its downright idiotic.
1. It was an example. Everyone knows that people have separate jobs in building this game but right now but no one appears to be working on the walls as even a priority. source rust trello
2. I disagree. It's a survival game. Kill or be killed. Build a home and protect that home. Conqueror or be conquered. It's the holy grail of Rust Legacy and why the game was so successful in "Alpha". The goal and what keeps coming back is to start with a rock and build to Kevlar/C4/Military weapons with a hard to raid base and conquer others. Without it, it's a boring ass minecraft game that is buggy as hell. The majority of people will go back to Legacy without it. And now, even with gather X mods, resource farming is very very slow.
