I'm sorry, I'm not sure why tactical discussion encourages metagaming?Kobu said:And I am not sure where you are getting your idea of it from since I haven't seen anyone express metagaming any other way than what SmCaudata wrote. It's using your knowledge as a player in a way that breaks from what your character would ordinarily do.
Having the game grind to a halt while the players sit around discussing where everyone is going to move to avoid attacks of opportunity, set up healing chains, or position characters to optimize or avoid areas of effects general involves metagaming and I think it takes a lot of fun out of the game.
The warlord as presented feels like it will be encouraging that sort of metagaming--like you have one player designated to look at the battle map like a chessboard. That player is meant to move his pieces around to best effect, and that includes moving pieces other players rightly feel are theirs to move as they please.
An attack of opportunity is an abstraction, so is an area effect.. While I'll grant that some usage of some knowledge in such a situation (A character with no knowledge or experience with the fireball spell, knowing the range and radius) I don't think there is anything inherent in the discussion that is metagaming.
