Having a starting point from which to build is really helpful, and that is where this massive archive of builds can come in handy:
http://herostats.sourceforge.net/files/Mids%20Builds%20Archives%201905.7zYou can find a Rebirth customized version of Mid's Hero-Builder which can read these files in this thread:

Note: Some of these builds are quite old and predate the inclusion of Stamina as an inherent power, and will generate an error message. This just means you can slot another power there.

Mods: if this is in the wrong place, feel free to move post. There was no option to add a post to Archetypes, only the various subtopics.
