Only unclear if you didn't properly read my previous post(s).
No, I didn't "invert" anything. I pointed out that 3 people were bashing me for something they themselves didn't comprehend.
So? What does that have to do with anything? I'm happy for you that you seem to have understood what I meant - if you had written that right away, instead of your cryptic one-sentence-response where you made it look like 1.5:0.5 strength should be the same as 3:1 combat odds, I might have excluded you from the list. But as it was, you were just the third person accusing me of mixing up the odds, and you were wrong. Just repeating what YOU have written later on will not change that (ozon at least had the decency to admit he overlooked something).
But obviously this leads now where, as such I will not respond that any longer.
About "spearman vs tank": As I have written before (see my post, #66), imo Civ, like any other game, is some form of abstraction, but also, again, a spearman unit beating a tank unit is actually quite realistic. Just look at the war in Iraq, where normal people with VERY limited resources take out one vehicle after another. So for me it stands to reason that a great commander would be able to organize some explosives and rig the area so that they destroy some tanks that foolishly went through a valley (or something like that).
So not only do I think it's somewhat realistic (not the galley vs. battleship, though, which I think should NOT happen, especially not as it does in Civ5), but I also it's good for the balancing since it gives the weaker civ some help. Still, the odds for something like this should be around 1%, not 10% or more.
