Sage special ability - too powerful or not?

With the expansion being out for a while now, I wanted to hear your thoughts on the sage special ability. I feel that it’s a bit too much as it’s essentially 2 specials combined into one - stunning the enemy myth unit, creating a temporary copy of the myth unit.

From in game experience I feel that this is too abusive, especially available that early - 3rd age, no other civ has such powerful hero abilities that early + you get 5 sages… I feel that they should have only one of those effects not both. I’m more partial to the stun than the doppelganger myself. What’s your take on it? Do you feel it’s fine as is?

I feel ya, it does feel easy to counter myths as chinese for me, just getting 1-2 sages and getting a free temporal “traitor” beacuse at a certain level the stun and copy makes it almost guarantee you will kill that myth unit. I would like the ability of the current sage to be kept only for the shennong mythic hero, who as of now pales in comparison with nuwa or fuxi and have the monk just clone, not really a fan of stunning abilities in general, and the clone aspect of it brings more flavor and strategy to it
