Guild Wars 2

I have a general idea, but I’m not 100% sure. Does this game have loot tables for each mob, or is it truly RNG? I know drops from dungeon chest and bosses guarantee the small loot bag with karma and some silver.

I think humanoids can drop bags which contain crafting mats. Any mob can drop any type of gear

It is a mix of both. Some mobs have a chance of dropping mob specific items such as bags and crafting materials. Anet has already started mob specific items at high levels (Final rest staff, shadow behemoth in queensdale, etc)
