Raid 5 no Hwa. What's your strategy?

*Been playing 2 years

*Finish C3-G1 weekly

*Can beat all other aspects of the game (TOA Hard, 2 min NB10/DB10/GB10)

Raid 4 is a cake walk and finish R5 about 60% of the time. Unfortunately RNG has never blessed me with Hwa despite 100+ pulls from SS over the past year during her rotation, countless fire scrolls and more mystic attempts than I know what to do with. Still no Hwa to be found... she is the final barrier to me solidifying my R5 team. Box

So for those of you who haven't been blessed with Hwa, what's your R5 strategy?
