Just a warning to everyone that Blizzards algorithm currently spawns order hall missions based on your highest item level champion, so if you upgrade 1 or 2 champions way ahead of everyone else, you're going to be in for a bad time.
I upgraded two champions to 810 in order to do the rare dungeon mission that was spawned. Since then (around 4 days ago) - I've had 1 mission spawn that was below 820 item level. My current available missions are: 820 825 825 830 830
My champions are: 760 760 790 810 810
Needless to say, it's been slow going. I also play one of the classes that has to successfully complete missions in order to get additional upgrade gear, so I can't even wait while work orders catch me up.
Also - has anyone that plays a class that does not have access to work orders for champion gear actually gotten an upgrade token from completing a mission through the Legion App? I've gotten them when completing them in game, but never through the app - I'm curious if it's bugged.
