So far the campaign has been going good but I wouldn’t autoresolve those attacks anymore. You might be able to get the battle fatigue to stack by doing a manual attack and immediately cease firing.
Those autoresolves are killing me. I was thinking I'd try some to up the difficulty on myself and burn through the fatigue, but it's not worth it. Attack and immediate cease fire feels a little gamey to me, but maybe if there's a supply cost I can justify it.
