We were blessed to have Darth Malgus's lightsaber added to the game. After almost 15 years shouldn't be the Will of the Force that Master Ven Zallow's weapon make its way to the Cartel Market? There are also many fan art designs that would prove to be a worthy addition to the game. The tech wizards and game developers possess the skill and Force Abilities to make these items available to us.
Swtor remains popular after all these years and, hopefully with more larger story expansions down the road, it will last even longer.
May the Force be with you all
