I actually really like Skadge. He is a nice change of pace, even though he's a bully and the storyline was a bit hokey with him forcing his way into your group.
Also, there were at least 2 companions that were killable in older beta. To kill them off, you had to basically keep choosing yes to kill them off for many conversation choices, and then in the end they died. However, BW decided this was ultimately a bad decision because it may limit your gameplay later (companion role, crafting, etc.). I indeed killed one off.
I particularly despise Ensign Temple, the low self-esteem girl who shouts "I'm strong!" while fighting enemies as a self-affirmation, and Ashara with her "With the force, I can do anything!" stupidity. I'll take Skadge over those any day.
