SWG - Dev Diary @ Official Site

Star Wars Galaxies game designer Thomas Eidson discusses NPC  balance in his latest developer diary.

When approaching a systemic issue such as creature balance, you would not normally modify only one statistic. Modifying one statistic for creature balance makes your creatures bland and boring during combat. Our current game does not rely on a single statistic for combat. We use a master data table that is level based, which means the statistics rise as the level increases.
