If you pick a base character then the prime gets removed as well, the better version cant exist without the base version, however if you remove a prime version then the base character can still exist. My personal pick would be Valkyr due to how [IMO] useless she seems
Nekros, not a huge fan of a loot bot frame that confuses other players in missions. Dont see it too often in SP, mainly just on dark sectors.
How does nekros confuse players though? He is pretty straightforward.
You think you are shooting an enemy but its a nekros mob
forget other players, I often wind up shooting my own shadows.
