It’s not ignored, it’s an old request since we introduced KD dragons - and has been addressed a number of times.
I am also currently swamped but even at the best of times, I cannot reply to every single feedback/discussion thread, even if I have read them > made note > told the team etc
Currently, we do not have plans to update the KD Dragon, introduce infinite mode or make any other changes KD fights. Should that change, I’ll try to share it in advance.
