"just a week" is 168 hours.
Don't forget that all people are not the same. Someone enjoying farming profession, chatting, helping others and only have roughly few hours per day not everyday.
Even if you play everyday for 2 hours daily it will take 3 month to just level. I don't tell about grinding proffs, gearing, and noobs like me who don't have a knowledge of everything who will die 100 times and make it longer, and leveling Character who you will eventually abandon for another.
Weirdos you describe is another problem, and making it x1 is not fixing it. It's called griefing and should be banned like bliz announce on official hardcore now.
Also, just make it pve with an option to turn on pvp if you'd like.
It's easy. It's 2023.
So many options.
