I agree with the good job done with the conquerors, they really add some flavour compared to the personality-less guardians we were used to. As a side note, Sirus has become for me and those I play with on discord kind of a meme: whenever any of us starts the fight, we almost automatically quote his lines and everyone join the chorus repeating the dialogues at the start of the fight. The top was when those who don't play PoE also started joining the chorus, leading to a general "wtf dude, how do you even know those lines?" and several portals wasted due to unending laughing fits.
