Just an FYI to further support defense issues. Landed 48 units on a backward Incan island. These were mainly T54 and T34. I took only one loss on offense, to a musket. On the IBT I lost a number of tanks to invisible units and one to a LB, again.
It would not be too bad, except these were mainly Enslavers and Priest, not even Lawyers. So it is atttack 2 and attack 3, killing tanks. The attacks were in the field, so I had no Lawyers to see what they were, but I brought up one for the next turn and saw a stack of about 10 of them.
Some of this is the crapping combat design, rng, that lets far inferior units win battles. Still tanks should not have a defense value of 6, they are to large of an investment for that. The engine should have been designed so that attack 2 does wins any battles against defense 6 and 7, let alone more than half of them.
I do not recall any archers killing rifles in C3C, let alone even better defenders. Civinator this is not your fault. Taketwo was going to correct the rng issue during 1.22, but ran out of time and money and pulled the plug.
