Tactics - maybe, but wisdom always! On maps larger than average, there is always an opportunity for Swamp and Barbarian to capture a castle of another faction and build the guild up to level 4-5. Not to mention that Earth magic books and so on, which are sometimes found in Dragon Utopia, become useless without Wisdom.
Archery is good for Tower. But for others, Attack ultimately gives a greater bonus to damage. For an archery army, Tactics is more useful for favorable positioning of the archers, and Defense for those who protect them.
...and their absence happens extremely rarely and on maps smaller than average. :)
