Xi Construct Hate

Why all the hate for Xi Constructs? Im going to be honest, I constantly see people, especially Disputed Origin hating on Xi Constructs and I have no clue why. He claims that they are the hardest TP boss, but I have never had an issue killing them. They are so easy to kill. They even have constructs that spawn on them so any AOE procs like gasoline do a ton of damage. So genuinely, why all the hate for them?
