Specialized Soloist (Badging character) advice
A Widow's not a bad idea, as Capa said its not quite complete stealth but easy to add the stealth IO or superspeed and then you are fine to go. With mezz protection and good defenses, you don't even have to worry that much about getting past things like Rikti Drones. I haven't found anything they can't solo pretty easily, especially with the choice of 2 builds to do so. And they will be more popular to add to a team for the badges you really need a team for then scrappers.
Soldier is also a good choice, for the same reason; stealth/solo missions with the Bane build, join teams with the Crab build.
It's reasonable and certainly better than SS, but no where near stalker-level. They will get seen when my main won't. (I do exclude Rularuu and Rikti Drones which laugh at Stalker Hide too.)
It always amuses me to watch one try and follow my stalker and then get seen. I can be mean like that.
EDIT:
If I'm reading Mids right, Stalker is 150ft, Mask Presence is 40ft. SS is 35ft.
