5e Spelljammer game

[GM Anthraxus]

Yeah, your build is just fine.  I was working under the assumption you were wanting to rejigger your equipment to make use of the Medium Armor proficiency.

From what I've read they do suggest buying Scalemail but my dex is too high.  Not complaining though.   I might be switching my Strength and Wisdom around.  Since I have an 18 dex for finesses weapons and a 19 cha for my Hexblade weapon, I don't see where I need a lot of strength.  I can boost it later through the stat boosts.  Wisdom seems like it would come in a lot handier for my bounty hunter skills like Perception and Insight.

Opinions?  Suggestions?  Anyone?

And, other than the stat their based upon, in your mind, what is the difference between Athletics and Acrobatics.  Online people are saying Athletics is the superior skill.  

And please don't take offence when I ask these questions.   I just like to know everything I can about a new game.  It's part of the reason why I'm having so much trouble with making a Dark Conspiracy character. But I do hope to get that done in the next couple of days.

No worries, I'm the same way.  Often Athletics and Acrobatics can be interchanged, but Vitkyng has a good breakdown there.  Athletics covers applications of strength such as:

• You attempt to climb a sheer or slippery cliff, avoid hazards while scaling a wall, or cling to a surface while something is trying to knock you off.
  
  
• You try to jump an unusually long distance or pull off a stunt midjump.
  
  
• You struggle to swim or stay afloat in treacherous currents, storm-tossed waves, or areas of thick seaweed. Or another creature tries to push or pull you underwater or otherwise interfere with your swimming.
  

Acrobatics covers your attempt to stay on your feet in a tricky situation, such as when you're trying to run across a sheet of ice, balance on a tightrope, or stay upright on a rocking ship's deck. The GM might also call for a Dexterity (Acrobatics) check to see if you can perform acrobatic stunts, including dives, rolls, somersaults, and flips.
