Good examples. I'm hoping that mirror image is just a placeholder. Same goes for invoke duplicity.
And yes, what Solasta has done correctly is a get the core rules down and *then* homebrew. (I'd actually like to see greenmage become an official 5th ed class) No one wants %100 RAW -- I'm fine with not having to finding diamonds to cast revivify, fine with changes to ranger class -- but getting things like find familiar correct would be nice.
