Training camps

I didn’t see this on another topic. Is the upgrade to the training camps to a level 21 going to guarantee a 5 star hero? Unlike level 20 where it’s a 3 to 5 star? Just asking so I’ll know what I’m gonna do. If I should level my stronghold right away. If not I’m gonna wait to level since it’ll be 8 days. Thank you for reading this.

SGG did have an advanced training in the works. It has since been scrapped for the hero academy. No information how it will work. I’d be surprised to see a guaranteed 5* though unless it had something to do with recycling other heroes.
