Thanks for the explanation. Sorry, missed the post at first. I wasn't aware that even after the 15% aura buff to everything the gap between burst and sustain phases is still bigger than on live. If that is how it ends up, then yes, they either failed or didn't inform us about what they really want to achieve.
I kinda still thought, they'll bring up our crit rates somewhat before this goes live, as they also (generally) mentioned in the last Q&A that you'd only lose a few percents of the secondary stats, which in the case of our crit rate is still not true.
I interpreted the various comments from the dev and CM that after the latest live nerf they thought fire is in a good spot. But at the moment, your interpretation seems to be closer to the truth. Anyway, thanks again for the explanation. I still hope it won't get as bad in the end. Really enjoyed fire so far.
