Curious what other think of the options...
The minor GM trait seems odd in that it feels like it could be baked directly into Mirage Cloak itself.
Infinite Horizon becoming the minor would make the remaining traits much more interesting for builds (without massively increasing the damage or utility of builds).
Elusive Mind having the exhaustion for such a long period feels extremely lackluster and simply gives up too much damage in general.
Dune Cloak is nearly exclusively for condition damage builds, but for all the usual builds seems to be a less good option than Infinite Horizon (which is why making it minor would be such a good choice).
Moving and adjusting Mirage Cloak and making Infinite Horizon the minor would free up a slot though, so perhaps making a power option for a grandmaster major would work. I suggest one that interacts with shattering mirrors to increase the damage of your next non basic attack ability, so that using the mirror creating utilities and Desert Distortion together for a bunch of mirrors means doing a bit more damage with direct damage. Such an ability could be called Through the Looking Glass and also affect the damage of each of your clones when activated as well, this makes interactions between the player and usage of their clones a bit more interesting. This also decouples the damage of Mirage from condition damage a little and opens up the gameplay (which being telegraphed a bit and somewhat able to be counter played in PvP or WvW scenarios).
Basically, while the damage for condition damage users is present and strong, for power it is a bit lacking. Increasing the damage and making it require skill to use and play around would open up a lot of play potential.
Does anyone else have thoughts on adding or rearranging some traits?
