I believe that 4 of those 6 ideas make sense. However, I disagree on point 2 and 3. I disagree on 2 because raising your light has to be a challenge not lowering your light makes it way to easy, but if you were to say trade a current piece of armor for the same quality from the faction vendor then it would be fine. Finally, I disagree with 3 because it would simply be easier to acquire the items that it says you need for the infusion, why pay more than you would have to if infusing yourself.
