If you're referring to dungeons, you can definitely eat at least one AOE and still be fine. I've done it quite a bit recently.
Are you perhaps hitting Wildfire > Hypercharge > HB Spam? If so, you're probably having trouble getting 6 Weaponskills in the Wildfire window because the first second or so is consumed by Hypercharge's animation lock.
You could try:
Wildfire > Regular Weaponskill > Hypercharge > HB Spam
or
Hypercharge > Wildfire > HB Spam > Regular Weaponskill
and you should have no trouble fitting in 6 skills, unless this ping problem I've heard about is WAY worse than I think it is. I've had zero issues fitting 6 Weaponskills in a Wildfire window using the first method. Can't say I've tried the 2nd.
Just wanted to throw that out there. Other than that, I'm 100% on board with
Typhoria's improvement suggestions.
