I don't think they actually intend for the offline gathering hall for 4 people because same hting happened in MHFU plenty of people played it solo and the monsters were harder in the gathering hall just the same. I think it's just meant to be harder in general.

Besides the final G monsters like LV140 and end game G3 ones have much much more attack power and HP than Caravan Quests so once you get to that point the realy hard stuff begins.
