I think there should be more Garrison Customization
One of the reasons garrisons failed so hard is the lack of customization available to us players i mean in the end all garrisons look the same
and its very boring..
imagine all the possibilities if they only focused more on customization rather than boring follower quests
for example i would like to have only white human followers in my garrison i mean i did it with my 25 followers but i cant change the random NPCs i still get some pandas,blacks,draeneis.
They could start by giving us a player house inside the garrison
the commander hall is not a proper house
So for conculusion
Imo we should definitely have the
1.Ability to change building styles
2.Ability to change the colors of the houses
3.Ability to plant trees and different vegetation
4.Ability to remove Specific NPCs
5.Ability to build our own home within the garrison
