GW Match Making

What the heck. Today I start GW and the VERY FIRST node has three 7*, one 6*, and one 5* all with purple gear and all at level 66. My team is at a similar level, but every time I've played the first node for the past few weeks, it's always been an easier team in the 50s and then progressively got harder and the final few battles were always a challenge and fun. I can't even beat the first node. They are destroying me. This is crazy. My best possible team can't do anything, even with a few healers. So frustrating. It always feels like one step forward, two steps back with this mode. I don't see what was wrong with how it was before. I don't know if there was some kind of hotfix or update I missed, or if this all works off some algorithm, but it really upsets me I can't get past the first node. For the record, my team is 7* Sid, 7* Luminara, 6* Phasma, 5* Old Daka, and 4* Dooku all with purple gear. Even when I plugged in my 6* Jedi Consular, I couldn't make a dent. Please check into this!
