I'm able to finish the wampa bounty ( sometimes with a restart from bad RNG) running an all-g11 squad. Bossk(L)/Boba/Dengar/Greedo/IG88 with only Bossk's lead zeta. Bossk has about +80 speed, Boba and Dengar around +90, and Greedo and 88 about +75. The trick with the wampa mission is to make sure your cooldown are completely ready for the last phase, and keep him stunned and/or TM controlled or he will one shot everyone except Bossk ( 2-3 hits for him). Dengar and boba need to be very fast to allow for the lead zeta prot Regen from their aoe debuffs specials.
