Multiple GA drop rates taper off, and are just too low

After playing for untold hours and making it to Pit 107 by sheer willpower, and spending countless gold and resources at blacksmith to rework masterworks, im very frustrated with the drop rates for items with multiple greater affixes. I havent seen a three star in who knows how many mobs- they were dropping a teeny bit after hitting 100 and then basically dried up, and the chance of finding one thats viable for a build is even more impossibly low. I want to know how many other (non casual, im asking the min 8hr a day folks here) players are frustrated with the drop rates particulary with greater affixes? maybe its just me… talking with people in random parties the quality of uber uniques is constantly underwhelming, 2 GA being incredibly, astronomically low (like .00001%?)
