How often do you beat galactic wars in a week

not sure what is going on then. I complete it every day (takes about 30 mins) I am level 80 but my max toon is 78 and my arena power is 27.5k I think they have changed the way Gw is calculated again. I do have a 12th node fully moded team every day. but I only ever lose 2 toons max. I run phasma lead, Rey, 88,ashoka and qgj.
