Done T7 with Boba g12 (speed 110, 222% crit+lead crit), Dengar g11 (speed 100ish), greedo g10 (speed 100ish), ig88 (speed 80ish), cad bane (speed 80ish)...the main factor was high efficiency of about 90% on most. Once dengar and greedo deployed successfully dropped their bombs chewie was instantly gone and after that han, rolo, lando and last but not least r2. Needed about 30 minutes with the arena mods. Before tried unsuccessfully with about 70 speed quite some time.
