Wonderbrazier Illusoryself is generally considered too powerful to have in the hands of everyone has an artifact. This differs from the skill because there is an opportunity cost associated with choosing a skillset (you forgo other skillsets while choosing glamours) whereas with the artifact, you can have it with any skillset. With that in mind, I don't think we need to consider changing the Glamours skill itself at this point in time, and any change will be limited to the Wonderbrazier.

Change it to a PvE only effect.
Change the amount of health the illusion takes (125% was offered but could be changed)
Change it to one-time damage absorption skill with a 30s cooldown on use. (Promotes strategic, high risk-high reward use)
