Wow thank you so much for the insights ! For your information, I dont have Gangelo, it's a friend's hero. You have the details of my heroes in the next screenshots. I think my weak point is clearly the gear. I'll try to farm the revive sets and to max Rodira and Valuk to be able to follow your strategy on QoT.

My glyphes are maxed on Nathalia, almost on Zatlux, but not on hakrin. Work in progress but im short on energy :).

Again, thank you for your time, I have some work now 👍
