But they can - and should - try their best to discover what opponents they are going to face through scouting, research, gathering information, etc.(Psi)SeveredHead said:Problem! I don't think you can compare the cleric's spells to favored enemy in terms of "changing per day".
A spell like prayer is useful every day. A ranger who picks aberrations as a favored enemy that day, and doesn't face any, completely wasted their ability.
Rangers don't get the ability to see the future.
Plus, the ranger should be able to obtain a good idea of the types of enemies he's going to face once he catches the flavor of the campaign or (on a smaller scale) the adventure. Unless the DM is running a scenario where the players have no time to rest (the spellcasters cannot recover spells, etc.), the ranger will be able to adapt his favored enemy choices and make them more useful.
