1. No. All the units for EB1 have been decided and will stay as they are; however, don't feel down because there will be Numidian regionals for you to use if you conquer the right territories.

2. No and probably not. Go take a look at the unofficial mod forum for these.

3. Everything is perfect, we do not make mistakes... j/k. Stats for units will still be fine-tuned, but the next release is still far off so get used to the way things are in 0.81a.
