QOL for MUS grinding:
For those who want to grind MUS while doing more common activities within the game, and not to devote specific game time to do just that:
Place an item/terminal in each OG heroic, that when a smuggler that is in group slices it, it spawns a boss fight. By killing that boss, a smuggler is awarded 10 MUS. So in each full heroic run, a smuggler can acquire 50 MUS. So 5 OGs equals 1 convoy run or two delivery missions. And it's content most can do/want to do.
Ideas for the bosses:
EK: Before the second boss room, a smuggler can slice a torch outside of the room. This will spawn a third critter boss along with the current three bosses in that room/boss fight.
AM: Upon entering the instance, there will be a tablet a smuggler player can radial and slice it. Along with Nandina and Gorvo, a spider boss spawns.
IG: Upon entering the instance, there will be two mouse droids. One starts the instance, the other when sliced will trigger a droideka stronger than usual, during the droideka fight.
ISD: the room where the extra boss on legends will have a boss, just like on legends.
TK: when first entering cantina during the clearing phase at the start, an item on the bar counter will spawn a second gold elite tusken.
As for loot drops, it can be the same as the loot from other bosses on those instances, which works as an incentive but not a must to bring a smuggler to OG runs.
