So several questions in no particular order.
1) When using progression points to add a trait, are you still limited to the 0-X from when you made the base model?
2) I have not looked at all the five factions, but from what I have seen so far there is no way to make a small model. Is this a case of based on model size you just say it is a small model, as I can also not see any buff it gets for being small?
3) If I have a trait/natural weapon or armor that is higher than my properties level does the model not get it at all or is it just caped at the properties level?
This is all for now, but I am sure there will be more as we get more into this game. Thank you.
1: Correct
1-1 Faction and Species are interchangeable in definition. So yes a faction trait everyone would get. Class traits only the class gets.
Mission Award only means you can only get it through a Mission Award. Mission Awards are dependent upon the mission you get.
2) Smaller models right now have no additional rules. There will be in the near future.
3) You are correct, just you max out at 2 properties but have Claws 4, then only the Claws 2 applies. There are some natural weapons and morphs that have the same enhancement bonus. These just stack within your maximum properties.
