Here's a question which has been on my mind since these threads have cropped up...
Should a smart GM have an advantage?
Would players object to monsters with low mental stats being played with a high level of tactical awareness? For sake of example, let's say the PCs are fighting a group of mindless zombies, and the zombies start to use advanced flanking maneuvers, react to contact with the PCs by adjusting their tactics in response to what the PCs use, and etc.
Another excellent point, that both PCs and NPCs are constraiined/advantaged by the people behind them, not their stats.
if the NPCs are "dumb" then what rules should the GM be following to constrain their tactics and actions.
Just as Hussar would consider it poor play for my 3 INT barbarian to be a tactical genius, that same standard must apply to his monsters.
By what metric might we all follow?
