This is a great question/suggestion. I will pass it on to the team.
Now that gear for companions is for aesthetics only, is it possible that we can get the old green starter gear back for them somehow? I know I have a few companions that came with gear that really fit their character, but because it was green it has since been vendored. Some of these it's especially hard to find appropriate gear for. For example, Lord Scourge. It's really not possible to recreate his original look because any gear that looks like that is restricted to the Imp side.
This is a good question, let me talk with the dev team and I will get back to you on this.
I would just like to know the impact of the presence stat on companions. Will it be changed and/or will it be similar to what it is now?
