I think I might have commented on the bubble following you. If I remember correctly and it wasn't someone else's post, I said something along the lines of how would you shoot enemies if the bubble followed you. I also agree with locking the subclass. I rarely change anything now that they are topped out. Except for when I equip starfire protocol since the game won't allow you to have 3 fusion grenades. That kind of bummed me out when I tried it the first time.
