Bugbears are the big bad goblinoids. A single average bugbear has always been more than a match for a single average goblin, in a straight up fight (which sort of fighting neither generally employs). As Dungeons & Dragons has changed and evolved over its many varied editions, the mechanisms of combat, the values of the statistics of the creatures involved, and the special properties of both Goblins and Bugbears have wandered significantly.
When I've got a band of bugbears running the show (as opposed the more leader-y hobgoblins), I usually want only to allow them to command about as many of their smaller cousins as they, as a group, could defeat at once in combat in favorable terrain conditions. Basically, the idea is that when the bugbears are outnumbered beyond a certain point it makes them and the goblins uncomfortable, because they are worried about potential rebellion (which would result in a goblin-led group with a couple bugbear warriors) and neither group likes the political instability (though individuals within the group might) nor the increased class tension and Bugbear-on-Goblin violence it brings.
That said, I have been wondering in what edition of D&D I might best be able to run an adventure with a largish group of goblins run by a smallish group of 8 adult bugbears such that the bugbears are most outnumbered by the goblins yet would be able to hold their own against the smaller kin in a chokepoint battle.
The bugbear leader and the secret ambitious goblin would-be king will have special stuff ala class levels or other upgrades as dependent upon edition paradigm, but the rest of each group is average.
What edition of D&D gets me the most Goblins per Bugbear?
