Strat only, I'd like to request. For battle and *especially* siege, they'll just aid in delaying the game.
Delaying is the fault of the team who says it.
Add it for everything, it will force people to use strategy. Pikers beind pavise? Cav actually being used to flank for once?
Dont cry the usual tears, come up with a better reason not to add it to battleor siege.
