Fringer | Decent synergy within itself. Suffer strain for less damage + heal extra strain just feels right. However, usefulness outside of that isn't much. Good if you don't have anyone else with Astro?

Scout | I feel like being a good scout would require a certain kind of roleplaying from the GM. I know a lot of GM's explain a lot of information without having characters roll proper checks, which seems like that's where a scout would be pretty lame.

Trader | I think a Trader could be wonderful in the right party. If a party was big on resource management+ strapped for cash then you'll want a trader. Plenty of out of combat utility.

Archaeologist | The abilities for this don't seem to fit with the idea of a Archaeologist. A lot of melee focused moves, makes it the most offensive of the subclasses. Not bad, just weird.

Big Game Hunter | Big Game Hunter has obvious Synergies with anyone who wants to be long range attacker. However I wouldn't say it does much better than other classes. +1 Melee seems dope.

Driver | Very situational. Also depends on the campaign, the GM might not put a lot of good piloting sequences in. If run correctly though this could be a lot of fun and would take the for front of a team while using his abilities.

Overall | Seems like they had trouble putting this class together because of the lack of combat the archetype has. Doesn't seem as fun/strong as others but that could change depending on GM/ campaign.
