My personal opinion is that you should be able to bitch slap morons already at the start, but sadly are the facts that there's plenty of "game-ruiners" in the start.
They're normally Pingers/DDosers, but when the game they want down doesn't go down even with heavy DDos, they find new ways to take it down, and it's so easy to make a few guys quit just by putting 10 minutes to exp.
When RPG server started, there was 5-6 guys from Classicus that came online and in the start and started killing all low lvls they could find in hope they would quit
if the server was 1x, max 2x and you had to do Rookgaard the hard way it would be less risk for those people and PVP could be active already from the start
If it helps, see it as you have 13 hours to lvl up now, before a guy who hunts you and can kill you in 1 eu is unbanished
To my opinion people can wait after the time then do the pinging n the ddossing still decrease the time from 13 to 2 hours at least.
