I feel this is way oversimplifying things and pigeonholing the roles of guilds. With a few exceptions, the amount of Order/Law/Good a guild has depends on its current players and leaders. Furthermore, guild dynamics constantly shifts. While some guilds are notorious long-term enemies (Paladins vs Chaotic-Lords), others shift their affiliations over time and wind up with perhaps surprising allies and foes (for example, War-Priests).
