I've been trying for a while now, and never got further than the final battle.
As a Mc cree player, i always get to the ramp, shooting whatever comes, when reaper spawn, i start my ult, ana ults me, and luckily, put him asleep, and even more luckily, no one wakes him up.
But i'm having trouble on the third boss spawn (junkrat then reaper). Since junkrat shoots everywhere, its impossible for Mccre to stand still while ulting, so Ana has to either put junkrat OR reaper asleep.
That putting the risk to waste Mc cree's ult into reaper's wraith...
Who/when should ana use her sleeping dart?
Am I completely wrong?
By the way, I'm putting mostly headshots, the actual problem isn't zomnics, its all about bosses
