[.950][Balance] Ythril Racial Trait
The Ythril racial bonus, unlike other racial bonuses, does not come with any penalties. Tarth's only works in small armies, Paridin gives -1hp per level, yada yada, while the Ythril both gain a special unit type and 20 str +1 attack - very powerful!
The No ranged weapons should be tied to their racial rather than being a civ penalty, (so that custom races can't exploit their amazing bonus) and the bonus axes should be tied to one of their other traits. The free warfare tech trait would be a good candidate.
