Mortal refreshment only works when you finish a downed player, where as mortal power works of both knocking someone and finishing a downed player
This is a problem because they are both mortal perks and should work the same, mortal refreshment is a dead perk in opr because theres no downed people to kill anymore and it doesnt proc off last hitting someone
Bump, have also experienced this in OPR and verified in war. Mortal refreshment does not work on downs or assists in war, only picking up kills off the ground.
