Is there a canon size for Sentries?

Hearsay. Its speculation, but its speculation that fits with what we know. I have no proof, which is why im only 70% confidant.

They explicitly said she was an OC designed around the same time as Orphea. But they didn’t want to do two OCs for Blizzcon and didn’t have her ready for launch anyways, so they wrote the story to hype up Orphea and stuck her on the back burner.

If they want OCs do hard, why not make a new game…

Cause then they would need to invest into the games design and probably run it by activision blizzard for approval of the project.

Easier to just throw your own ideas into heroes.

They did, it was called Heroes of the Storm.

Not exactly HotS’ original purpose though.
