balancing of Deadlock (a study for university)

I'm writing a uni paper on game balancing (buffs, nerfs, reworks) and how they affect the game META. I chose this game because of the constant patch notes and the game being in early development. Were you guys ever frustrated by the constant changes? Did some balancing frustrate you? Has someone quit the game as a result of such? If you are willing to write your heart out, I owe you my life and my degree. Thank you so much
