CHEWIE T7 HELP no dengar

Hi Guys i need help with wookiee tier 7, i have zBossk gear 12, zJango gear 12, Boba gear 12, Embo gear 11, Aurra gear 10

I cant get a sniff closest i have been is i took han down and got my payouts but then got destroyed

Can anybody help with Mods and what i should have on and also strategy, i have read through the ones already up but it seems its all about Dengar and i only have him 5 stars

Surely i must be able to do it with 2 zetas and highly geared characters?

Have attached pics of mods and stats
