The devs would have to be willing to write something for the alliance and since legion, they haven’t been willing to do anything other than corrupted wishes or teasing.
It’s been that way since Legion, where the devs’ joke with ally began, at the Nightbornes event, where whatever happens, alliance always leaves with the perception of having received the worst.
First the Nightbornes that the alliance helped as much as the Horde, choose the Horde because Tyrande was mean to them.
It made all the time I spent helping this race a waste of time.
So in bfA we were ‘gifted’ with the biggest jokes that so far generate a bad feeling in the horde. Purple blood elves being sold as a placebo for High Elves. Not even lore thought to create for something pulled from thin air.
The only merit of this band-aid is to have the same model as the blood elves.
Now we have to hear, silent, that the alliance stole something from the horde.
Then we had junkgnomes and Kultirans. Something that didn’t give the same welfare and satisfaction to the alliance as Vulperas and Zandalares, because they only had to fill the horde gap by getting 2 new races.
Vulperas at least help the horde in Zandalar.
Junkgnomes? They appeared in a completely ignoreable filler to justify the pathfinder and so they stayed. Nor to show up in the heart chamber with some bizarre tech help.
In the end, the situation has reached such a point where it seems common sense that the alliance is a bankrupt faction and that its members have to go into the horde like homeless beggars because the blizard left the faction with no perspective or value to exist anymore. that we always appear to help the horde as servants.
It got so disheartening that any race that appears has to be discarded from the alliance.
Saberon? Not because they are more suited to the Horde. Sethrak? The lore created by Blizzard ignores the alliance and makes them have more sense in the horde.
Never for the alliance. It’s too good for the blue faction.
Arakkoas? Combine with the Horde.
Vrykul? They are more suited to the Horde. Vrykuls hate humans just like blood elves. We may have to paint vrykuls purple.
The faction is morally dead. I can’t defend the faction I like anymore because blizzard made it worthless and anything you think about doing to change that will end up hurting the horde.
If we ever have draconics, you can bet an arm like them or they’ll either have to be horde exclusive or pandaren, and have any development buried.
Just give sethraks to the Horde and some human with striking body proportions, a gnome made of wood or orange blood elf to the ally, or dissolve the loser faction right away.
Have Mercy.
