So I have noticed that I am unable to get Xalek's shield chance or shield absorption raised at all. Now is this a bug where we just aren't seeing the numbers but in combat they are actually working,or is it not working at all? For a tank companion he is awfully squishy.

Everytime I read QQ post like this it reminds me of this youtube video. http://youtu.be/i5tWT6I1GvY
