I was under the impression that this would come at release, did I completely misunderstand or am I missing the ability to make / use homebrew content?

Sorry as I know someone in one of the mega threads probably already asked today

Nope - The rest of homebrew are post-release features. 

Not right know, but homebrew races and sub-classes should be on in the near future. I don't know a date though.

Subscription means next to nothing for me then /sadface

Guess I will wait, as most of my campaigns think outside the box, while all the tools would be great, the inability to use the software to its fullest is wasted

Thanks guys for the quick response
