You forgot Krog. He's always a safe option.
About Groth, who is this character? (I don't remember anyone with this name in game, if he is a new character from the new event, no spoilers please I haven't played yet).
Groth is the lizardman character, right?
I think you're thinking of Rhot, Groth is an orc you meet in the wasteland.
Isnt called Groth? I mean the other Orc we meet in the wastelands. He´s got one of tusks broken.
Orc you meet in the wasteland, not involved in the new event with Logan at all.
