I guess we just don't understand what you are saying or others as well. The first sentence says that it is possible but Incredibly Rare. A few posts later they were saying that it happens 5% to 10% of the time. I think it is more often than that but even if it is 10% of the time that isn't incredibly rare. Incredibly Rare would be something like 1 in 1000 or more.
Whatever though... the whole debate is pointless. Those that believe Nubia is Stronger than the Aztecs aren't going to change their minds and vice versa.
The problem is you are selectively reading what I wrote.
The argument was focusing on early game rushes that happen between turns 10 and 14. I was saying that for me, that means a rush by an AI civ with like 5 to 6 warriors. That is a typical AI rush that can be a challenge. However, that is not common between turn 10 and 14.
Some other people were wanting to include barb rushes between 10 and 14 in that discussion. My point was I don't count those because they are easy to deal with. The only way I would count that is if you got rushed by 2 barb camps at once in turn 10 to 14. Again, not common.
Understood?
