pretty useless really, the main aspect of FOnline is PvP really, and AFAIK there are still some WM squares that have absolutely no encounters in them (not counting the impassable terrain or towns). The game needs to be balanced out first IMO though and hav more variety added to it, because >100 different enemy parties in encounters total just isn't gonna cut it in the long run, there has to be more variable enemies, and more versatile enemies, not to mention more enslavables with different stats...
Just My Two Cents Really...
