So out of idle curiosity..
If I was to play an Adaptive leader, and pick 'Aggressive' for my adaptive trait, and then build me a hero.. He'd start with Combat I, of course. Provided he was the right type, and all. But let's assume he is, so he/she starts with Combat I. I then proceed to chunk out Combat promotions until I can buy Heroic Attack/Defense..
And then I switch my Adaptive trait from Aggressive to something else. What happens then? His Combat promotions would conceivably drop to IV, which is insufficient to match the prerequisites for Heroic Attack/Defense. Same question goes for any similar promotions really, like Shock I etc.
Just curious, and all. I have way too much boring idle time on my hands at work..
