Why did you bother taking the hits of the subclass if you had no interest in using it then?
The hits? You mean, lower recruitment capacity? I was hiring from the best infantry troops at the time, and didn't have the income to recruit up to my maximum warrior limit. Are there any other?
It also (probably erroneously) made me feel overall safer from capture. And I figured that maybe one day, I'd train, or that, who knows, maybe eventually an occasion would appear where infil acts would be well worth the risks of being untrained (such as a huge army approaching a city and doing some road travel time play).
