What are your impressions on the new Mythic Boss mode?

My thoughts
1) It's cool to be able to do further upgrades using reown... but I didn't save up my reowns previously, used it recklessly to max up other character skills (just for completeness). =X
2) The BIG issue I dislike about this new upgrade is that there is no undo button. 
I used up ALL the reowns to power up my nature team... but it would be cool if I can undo in future and power a fire team or something.
3) There are characters that are outrageously strong.
One example is Bruken... just maximise the lightning bolt skill and lightning bolt equipment. And hope to get a lightning bolt hit neighbour upgrade.
4) The mythic fights are ok, but there's no replay value... fighting the same mythic boss stage again gives you like... 2 reowns?
5) All in all, it was fun for a while, but it gets boring fast.

So ya, I guessed it's time to quit this mode. 
What about you? Your thoughts, or any strong teams you created?

the upgrades you do on a character with renown is permanent? so i can upgrade my mercs with renown, without risking the upgrades will be lost? and untill which level can i upgrade them?

The upgrades are permanent and I believe it's infinite. The other thread that showcased the fight had level 46 on Medhiv staff.

 Have you tried the scaling? At the top there is an option to go to level(?) 100 and that will probably make it harder and increase the rewards.

The scaling seems linearly proportional to me, at least for those I tried, though the required reown cost goes up exponentially.
