KF totems good enough for uber feared?

Planning to get into ubers asap during the event but not sure if KF totems is the right angle. Anyone got pobs from event or mirage? Pretty comfortable with dodging the big mechanics but not sure about the chip sustain etc.

Initial thoughts are paladin into boss farming until enough for key pieces so it doesn't need to be dirt cheap, but reasonable day 3 gear.

TIA.
