What I was thinking was more along the lines of general starting zone. 
A jumbled mix of monsters wandering between the start and the surrounding area of bulls run. A chance to get players familiar with them before they go into the proper zones.
The forested areas and the gorge house monsters with intelligence. Hunt in packs, territorial, elite mobs and mini bosses, all with a big aggro range.
The fields of bulls run are littered with unaggressive trial monsters.
