Yeah, I know, wrong setting - However, since personal shields are a new thing in the Star Trek universe, lore-wise, and since these shields block ranged weapons only, it would make sense for both klingon and federation characters to have a heavier emphasis on melee combat than before.
Klingons, getting the Bat'leth, fine. I'd even be fine with having the weapon be restricted to the klingon race (not faction, but race) only. I would like to see more options for melee though, even if it's just stylistically.
The TOS era martial arts that feds get are fine and dandy, but Hikaru Sulu was noted as being a fencer, both in the original series, and in the new movie. There are a host of Vulcan weapons, and I am sure that there is more than one style of martial arts practiced across the galaxy.
Not looking for a game advantage, but it would add a lot to the game to have more options for style in regards to melee combat.
