GW matchmaking is still terrible

No I agree the matchmaking is awful, I only have 3 7 star characters and yet I am facing all 7 star gear level 8 teams from node 6 onwards, I now have a pretty deep roster and a lot of level 70s but since I got IG-86 to 7 star on Saturday the difficulty of GW seems to have ramped up tenfold. I have been playing daily since December and have only managed to complete this 6 times, I've tried retreating, tried mixing up the squads, it doesn't matter a team of 7 star gear level 8 Jedi with Qui Gon as lead can obliterate 2 or more of my decent squads and will usually take at least one or two of my A team with them, then the next node 7 star gear level 8 Poe, Sidious, Dooku, Luminara and Geonoshian #impossible. The only nodes you should be facing max squads on are the last two or three the rest should be a gradual increase in difficulty to at least give us half a chance
