Faction and Aggro

[dcl]

Got a couple of questions, that I hope someone can answer.

On Faction:

Looking at the Faction Table in the database, I see that there is a base faction and many mods. Does anyone know what the acceptable range for base faction is? (ie. what number is going to represent KOS?). The mods are labeled as Mod_c1 - Mod_c15 (presumably class modifiers) Mod_r1 - Mod_r14 (presumably racial modifiers) Then several nonsequential Mod_r## (which I assume are religious modifiers). Does anyone have a list of what specific class/race/religion each of these represent?

On Aggro:

Are mobs supposed to be assisting one another? Because on my server they are not. I can walk up to a group of mobs, and as long as I'm not KOS to them, I can fight one in the middle of the group and the others will stand by and do nothing. I thought that was what the Social entry in the NPC Table was for. Is there something I need to do to turn this on, or is it not implemented yet?

Thanks for any help.
