Been running R4 for a while and recently jumped to R5. The thing is, my team wipes usually during the last jump. I feel like I have a pretty safe team comp so I'm guessing it's stats. My team currently is:

Frontline: XF (24.7k HP, 2k DEF) Darion (26.6k HP, 1.5k DEF)

Backline: Kona (23k HP, 840 DEF, 194 SPD, 60 RES) Mihyang (19k HP, 910 DEF, 182 SPD, 1.8k ATK, 75 RES) Hwa (17.8k HP, 910 DEF, 190 SPD, 1.5k ATK) Colleen (22.9k HP, 650 DEF, 177 SPD, 60 RES)

I realize that I only have 1 DPS but if I can't handle R5 with this team then I cant afford to add another one. Maybe I should stick with R4 until I can have 2 DPS?

Anyways, Kona, Colleen, and Mihyang are on Vio and the rest are on 2 rune sets. And the only one with 2,4,6 maxed is Mihyang, so I can raise everyone's defensive stats a little bit more. But looking at it again it looks like my problem may be speed? Especially on Colleen, I believe I can get her SPD up more, along with her defensive stats, if I drop Vio.

Also, my Mihyang doesn't have skill ups. I 6'd her thinking she'd help a bunch with my team, but I'm kind of regretting her now. Is she just a late R5 mon?

Anyways, any suggestions would be appreciated!
