I think the problem people are missing with this is that CG have said the only old characters they are updating are ones that have fallen out of use or are in need of a rework. Omicrons are their way of reworking old characters, without having another Vader situation on their hands. Shaak Clones/Bad Batch do not fall into the category of needing an Omicron, so I don't see why they would give them one.
In terms of improvements to LSTB, I would much rather they added a button to 'apply all mod loadouts in this tab'. That way you still need good mods, and it takes time to create the loadouts, but after that point it's much faster to apply all the loadouts. Instead, you currently have to go individually to each character, and then do the same for every character that's missing a single mod after the TB is over, and then do this all over again the next month. Such a small update that would save so much time and go some way to making mods not the most boring part of the game.
