I'm lvl71, i got several daily challenges, one is "Complete 2 purge missions in a row within 30 minutes, at least 4 levels higher".
So i need to do 2 lvl75 purge mission. I check star map : nothing bigger than 60. I check Mission Deployement, nothing bigger than 70.
With tarrot card i can increase level to 72 - 80 - 90.
I can't do 90, 80 are too dangerous and long for me to do 2 purge in half an hour for sure.
So, have i to do these challenge with big luck on warzone/void crusade missions and get 2 purges at same time ? Do i have to them on rerolls ? If there is no "simple" solution that's clearly bad design...
