For TB (no trooper only mission phases) I use two empire teams.
Krennic(L)/death/shore/veers/snow
Snow will be replaced by starck once he is geared enough, ditto for storm and shore
EP/tarkin/thrawn/royal guard/TFP. I don't have zeta thrawn lead, and I've found the TM/health/potency combined with rebel debuffs from EP lead more reliable than thrawn lead. When storm is geared, shore will be swapped in for RG.
I haven't had any dropped waves so far in DSTB with them, even with a grand total of 0 zetas on either. The constant ability block from krennic lead is massively helpful. Obviously platoons can force substitutions, but they are both pretty flexible with subs.
