The 'Oldschool' community servers are great, they are whitelisted to keep out random hackers but the whitelist isn't too hard to archieve to never get into it. It's first-person only, so no more people sitting on roof tops looking over the edge with third person, only peeking to take the shot. A lot of people dislike the first person in DayZ, but I honestly love it especially when you adjust the FoV to the settings you are comfortable with. I am so used to it now, when occasionally joining third person servers I feel more comfortable using first person, but always feel regret because the enemy is gonna have a big advantage.
