That'll be good, if we can get enough flavour with just 2 traits (and not unbalance the ones with 3).I'd suggest to drop the ones in the categories 'Probably not' and 'Out' and try to give every leader 2 traits (some can have three, depending on leader and specific traits).
Seafaring is obvious, but which one is Skirmisher?Also, based on T_F's post, I'd like to suggest the following two traits to be added (exact details open for discussion, but you should be able to get the gist of it from the name):
- Seafaring
- Skirmisher
