The problem is alts. Because with alst, people don't interact between themselfs. They have their powerbuilds and some alts to support them.I would bring there classic registration and 1 account per person/1 char on character.
Relog time 1 hour please!!!11
if by relog you mean: logging a diffrent character
But actually it's a really good suggestion. Once PvP builds will be able to craft PK suitable equipement without need to drasticly lower their fighting skills, we shall have less alts in use, and maybe more actual roleplaying.
using fast relogs anyway
And how is it working? So one of them can gather ore/minerals at ~x10 speed by reloging with each character which standing near rocks? And what's that? I.P. changing? Then they can also dual log easily, and x5 log, and then using around 50 alts one guy can gather resources at x50 speed.Edit: And if you're about friend(s)'s computer(s), then it's thier problem, it's the same, if you have friend who can craft an armor and a friend who can craft drugs.
and i heard that you can just copy fonline directory into another place, and that will work also.
