I want to change perspective and come at this as a player for a minute, since I GM a lot more than I play. It might help me better understand that needs and intents of those players that declare "I roll perception! ::clatter::"
If I am a player and in a circumstance that feel precarious, my first instinct is to declare something like, "I draw my weapons and prepare for anything." If I am being honest, that's pretty vague (except the weapons part).
I want to ask
@Charlaquin and
@GMforPowergamers and anyone else how you would respond to that declaration.
