I prefer hobgoblins to orcs, just because they're more tactical/intelligent. I kinda wish they didn't come with the whole "goblinoid" baggage, but what're you going to do? Not a huge fan of semi-sentient plant life.
Bugbear 21 Gelatinous Cube 20 -clearly the most underutilized "fodder" of all time.
Gnoll 20
Goblin 22
Hobgoblin 21 Kobold 19 -soooo effin' sick of these things being compared to/put en par with things like hobgoblins and bugbears. Yeah, they're cute dog-faced rat-tailed lil' buggers. Yeah, they can be cunning trapmakers and utilized effectively (so can goblins or anyone else. That just depends on the DM). Fanatical draconic stormtroopers?? No.
