I do my garrisons 1-2 times a day generally and over the last couple weeks noticed my paladin gets most of the gold missions vs my druid
my druid has almost all maxed followers... my paladin has random ones with worse gear and not all maxed.
they both have the same buildings for the most part I believe.
tavern, barracks, war mill, salvage yard. might have some random profession ones that are different

just seems odd that my character with all the maxed out followers rarely gets the gold missions and my paladin seems to constantly get them.

wondering if there is anything that is helping or if it is just really odd luck.

It can be a little random.
I run 13 level 3 garrisons with all having Inn's (Inn's or what ever the Horde versions called) give more gold missions.

Some gold missions will spawn more on some characters because of a hotfix Blizzard did to lessen the gold gained (not by much but a lot less then it used to be).
With only two garrisons it will seem very lopsided.

I make about 130,000G a month with my garrisons with just the gold missions.
