I think this class is really cool! Definitely better than their 1e version. I think that Get Em' could certainly use a buff considering its -1 circumstance penalty is easily overridden by several effects such as, but not limited to, off-guard(even if since it's a circumstance penalty and therefore can stack with things like Frightened which is a 100% good game design). When you factor in the fact that, even though it is a support class, it is still a martial class and if its core damage feature is something that doesn't scale with certain weapons traits, and is in fact worse than them, then it will probably feel bad to play comparatively-skill monkey or not. I second that the class is potentially a little MAD wanting high charisma, high dex, and depending on build, either high int, wisdom, or even strength. I disagree with the solution proposed by giving different key attribute options based off of leadership style as from what I can tell the design goal is to give the envoy more flexibility and diverse options, not allow them to specialize akin to something like the rogue's rackets. The class is definitely solid though and I think my favorite feature has to be Adaptive Talent allowing the envoy to share the same niche as rogue yet in a completely different way, and my favorite feat is probably Pardon Me! for its clever twist on Tumble Behind that feels uniquely Starfinder and is quite frankly hilarious.
