Just now, keltheos said:I have a feeling we're overthinking this one.
[joke] I don't know about that. That depends on what you mean by overthinking. Is overthinking thinking too much about something, or is it about thinking beyond it, like you overshot it? That could really influence whether we're really overthinking it or not. [/joke]
Yeah, you may be right. But then, there are still unanswered questions. I agree with @kaffis that it would be weird for the back rank strength to get higher after more units are defeated.
