is the spawn of these missions completely random?
I have 25 lvl100 followers and almost all at 645, did 2 highmaul missions, 5 grandiose missions so far but I have not seen a grandiose mission in probably 2 weeks.
On my twink I have mostly lvl100 followers, 4x645, did the highmaul mission and have yet to see any grandiose mission at all.
Is there a trigger for these missions?
On my twink I have not bothered with daily CMs and on my main I have stopped bothering with CMs for a while.
