Heroes were viewed by many as a significant gameplay modification introduced by "Nightfall". Heroes were commended for allowing the player more flexibility and choice in the game, but were also felt to be a mixed blessing because, unlike henchmen, heroes require micro-management, and often take slots in the party which might normally be filled by human players. Many commented that it seemed that the game was now more solo player focused than previous installments, Eurogamer suggested heroes bring ""Guild Wars" closer to the party-based RPGs of old ... instead of the solo-but-with-people RPG that it had initially delivered."
