In a 50 person guild, everyone should be responsible for 2%, which is about 1M. You doing 2M is the equivalent of two players, so it's certainly good.
There are a bunch of variants you can run:
Admiral Ackbar (L), Leia, Thrawn, Hermit Yoda, a non-Rebel Tank
Nute, Leia, Sabine, Thrawn/Hermit Yoda, General Kenobi
General Kenobi, Hermit Yoda, Grand Master Yoda, Ezra, Bariss
zPalpatine, Vader, Sion, Nihilus, Sith Marauder
Veers, Magma Trooper/Range Trooper, Snow Trooper, Colonel Stark, Shore Trooper
KRU, FO Executioner, FO Stormtrooper, Kylo Ren, FOSF Pilot/FO Pilot
Bossk, Boba Fett, Dengar, Greedo, Cad Bane
Boba Fett, Sabine, Young Han Solo/Wampa, General Kenobi/Sun Fac, Hermit Yoda/Thrawn
the squads you run should depend on the available characters you have, their gear levels, and zetas.
Good luck!
