Orks are mustering after Meros killed most of them the first time, so I would reason that this means that there is a chance that the attack will be delayed by a turn. Also, Alectai knowing when the attack happens is quite important for our not used to war peaceful craftsmen, because surprise could make them drop their weapons (or something like that).
Also, even if the timing question is not so useful, we could and should talk about the forces that will attack Meros, how many of them there are, the types of units that will be used, etc.
We need to (partially) counter our debuff to military and given that we can't yet just throw a shit ton of tanks at it, we should use seers for it.
