The rough estimates for a single Rogue running AW comes out to something like 25% wizzies killed per 60 stealth, little more for Faes, if every AW connects and hits the cap, so for a kingdom with a limited number of Rogues it will take quite a bit of AW to really wreck a mage's spellcasting ability (and the mage can still target fattening attackers, and still has an army to contend with... even a fairly bad kingdom can implement contingency plans for their Mystics).
If you are looking at a 3-4 day war and want to maximize your gains / utility, AW isn't always the best course of action to win in that timeframe, particularly against tough targets, and there is some utility in having more military on something like Half/Rogue. (I assumed Half/Rogue was the OP's superthief, but Fae/Rogue probably would want closer to 5-6 rTPA against Elves and other Faes.)
I'm guessing, like most players, OP realized that thieves aren't going to succeed 100% of their ops from the outset, and it isn't just ghettos that suffer from fails. (I suppose that depends on whether Simians counts as a ghetto, but I remember a quite hilarious thread a few ages back...)
