I did some polls a month ago and those are the result:
Kruber: Need to be a ranged weapon
Bardin: Melee or Doomseeker (Axe on chains, which technically never had the requirement of being a Slayer to use), Bardin technically has most of his weapon already and should soon start getting variant of his already preset weapon
Kerrilian: Melee (Take into account I’ve forgot the Shielded option) and from either of the elfs faction (vote was equal on it)
Saltzpyre: Melee or Melee/shield
Sienna: Melee (With either: Ranged Special or Support or nothing)
As for the weapon pack there, they are kind of cheap/lazy, like Bardin’s is just a copied H&H and A&A mixed together (then they could even introduce a reversed A&H (H&A)
Bardin’s Doomseeker: Second Slot weapon, work as a pseudo-ranged and has a wide arc of hit but is weak against armour (Available for Slayer 100%, OE 50%, Ranger 50%, IronB 25%)
Kruber’s Cavalry Set: Second Slot weapon, Either 2 Pistol (Like Saltz’s BoP) or a Pistol and a Cav. Sword (Like Saltz’s Flail) but still with an ammo counter, letting you use you pistol for greater damage than the Flail’s one
Kruber’s Arbalest: Second Slot weapon, the heaviest Crossbow in the game, take some time to reload and give a mov. debuff but devastating Damage and penetration
Kruber’s Grenade Launcher Blunderbuss: Second Slot weapon, Like the TH Torpedoes, low ammo count but instead of being very hard hitting it’s a bigger AoE (Or his could do less damage but have more ammo)
Kerrilian’s Draich/Exe. Sword: First Slot Weapon, work like Kruber’s Executioner sword
Kerillian’s Asrai Spear(With Sword): First Slot Weapon, A Wood Elf Spear, very spinny and agressive
Kerillian’s Halberd: A Halberd, what else can I say :{
Kerillain’s Beastmaster Spear: First Slot Weapon, A Spear and a whip, used to control beasts in Karond Kar
Saltz’ Sword and Buckler: First Slot Weapon, a weapon set very much dependent on countering people
Saltz’s Hammer: First Slot Weapon, Would most likely come if the Warrior Priest Career happen
Salt’s Hochland Rifle: Second Slot weapon, basically a Sniper for the Empire, very hard hitting but it has a slow reload time (Also Head Shot focus)
Saltz’s Comet Flail: First Slot Weapon, a Two handed Flail with 2 heads, still does what a flail does but is heavier
Sienna’s option are more difficult to say so it’s easier if you look in the linked topics
