Well, I'll let you in on how brokenly easy everything is and how I'm basically having to make up my own rules.
In the current party, there's 6 players, each level 1. Because of that, your 'average level' is of course 1, and for having 6 players, you get a +1, which makes the 'Challenge Rating' of an encounter to 2.
For that rank, it scores you 600 exp for the encounter.
For 'Epic Rank' challenge you get +3 to CR, which puts you at 5, and on the chart that's 1,600 exp.
A goblin is 135 exp - for 600 exp I could place 4-5 of them. Goblins are Small creatures carrying poor armor and weapons and poor stats. The individual CR of a goblin is 1/3 (which btw, 4-5 goblins would sum up to 1+1/3 or 1+2/3 CR, which is short of the 2 CR rating, so whatever). Using the 'cheat sheet' if we take that we've got 4 of the same creature it's +4 CR, so some sort of 4+1/3 CR? The numbers get confusing.
Either way, basic point is that your 'at level' encounter would give creatures much MUCH weaker than an individual adventurer, AND there's not even 1 for each player! Even at 'Epic Level' difficulty, that's about 12 generic goblins, 2 for each and still fairly weak, considering they're little stupid goblins.
For contrast, the encounter I've actually made is 16 goblins and 2 'similar to hobgoblins' (but not quite identical) because I just tossed whatever stats I could find, but they're being played as 'very large goblins'. In ranking, that's a 6 CR encounter that should be so far above you. Instead, between Bless, 20 str, Eidolons, and archers, you're doing an incredibly decent job of wiping the floor with the whole fort.
The default difficulty rating is incredibly easy and worthless. The rankings are on Easy, Average, Challenging, Hard, and Epic, going from -1 to +3 along the line. You're currently playing on 'Roguelike' difficulty of +4.
Needless to say, I'm making no easy passes here. If you're assaulting a goblin encampment then it'll be a fight. If you're not fearing for your life, then it's just free exp.
