i place my bets on andaba. one good plan is that high lvls stay up front while low lvls stay at the Governor's Mansion just in case. tee high lvls obviously have to split in groups. some medium lvls can stay somewhere in the middle of the city and guard from the staircases, able to throw grenades, daggers, etc
ADDED : But heres the worst case scenario : a couple of high lvls ( 10 in number ), enter a server where there are a lot of noobs in PR. each of them go either offline, or to another server. now if the noobs were hundred in number. Well lets just say that those pirates were left taking on a hundred undead, and nothing was heard of them ever again
