The lvl 300 paragon grind? How!?

hey everyone,

how is everyone doing this seasons 300 grind?! I switched from necro to paladin after purchasing the dlc just after Xmas and im at around 260 but the grind is so real!

ive joined groups that are just farming bosses over and over but once we all run out of keys to open the chests it stops..it seems slow and boring!

theres gotta be something? but hell tides barely seems to make the bar move!
