Sure there were! For example, in 2nd edition, the rules for Troll encounters were contained in the Troll entry of the Monstrous Manual (or equivalent MC):
But that's not particularly useful in determining if an encounter is balanced or a fair fight. Determining if the players can reasonably beat the trolls or not.You use this data to decide where troll encounters are appropriate (pretty much anywhere uncivilized), what strength they come in (1-12 of them), what objectives they probably have (satisfying ravenous hunger), and what's left over after you kill them (probably a bit of cheap treasure and some mostly-eaten humanoid corpses).
Knowing that trolls appear in groups of 1-12 isn't particularly useful.
The numbers were handy for knowing how many orcs were in a warband and the like, but for monsters... less so.
It's different.But the better approach is the old-school approach of just creating the world as it is, and letting the players be the ones who tailor their actions to the situation as appropriate. Having the world tailor itself to the PCs' expected actions is weird and backward.
Whether or not it's "better" depends on the type of game you want and personal taste.
