My two cents noone asked for...Wranduin edition.
Prior interests, easy solutions:
Ive read in posts that Anduin has shown interest in girls before (like a gnome and a dwarf) and a human girl named Tess, if Im not mistaken. And while this hints at a preference, its not really relevant, as he is a teen, and teens easily develop crushes. (even if he didnt show interests in boys before, maybe he just didnt find anyone interesting enough, or developed this preference later, could be anything) This doesnt even have to be redconnd
Either treat it as it was, random crushes of a teenager, or (Im not sure on the details but Im pretty sure his mom is dead) him seeing his mother in those girls, only realizing this later (mommy issues). Im not even sure what happened to those interests, I think those were from a book, which is already to be taken with a grain of salt unless it is actively in the game (at least in my opinion) I think Tess is in the game, what happened to her?Â
In any case, instead of making a drama out of it, with jealousy and hurt, it could easily lead to infinitely more interesting story arcs. (one of which Ill probably elaborate in another post)
Age gap. Homo bad, hetero good?
Wrathions age is awkward. I dont know the details but from what I could gather from posts he is 2 to 5 years old. Im also not sure if dragon aging has ever been explained in game.
Which doesnt really matter because Blizzard decided to not only give this whelp an adult human avatar, he also has the wits and behaviours (as far as I can tell) of an adult. While one can disregard the human avatar, since, from what I can tell, they choose their form, so he could just choose to look adult to not be treated like a child, he is way too smart and knowledgeable for a toddler.
Huge age gaps especially when a minor is involved is a bad thing, but in this case its between a dragon whelp and a teenage human boy. Both relatively young, plus the unclear aging of dragons. One could try to explain it like dog to human years, if you will. 2 dog years are 14 human years, which would make a 2 year old dog and a 14 year old human the same age. Then you could argue that dragons live a  long ass time though so why would they  grow up so fast, to which you could point to long living beings like turtles. Nature (especially in a fantasy environment) can be whatever really.
Imo, it does work, I do understand though when people reject this ship because of the confusing age gap.
But while I understand why, I also doubt this would be much of an issue if one of the characters were a female, seeing as loli relations are rather popular and weirdly tolerated.
Male friendships in peril:
An argument Ive read a lot, not only about this ship but any gay ship in any media, is, that the people who want representation, are trying to erase male friendships.
With thousands upon thousands upon millions upon billions of media, to this day moving forward, that involve two men being hetero friends, people dare claim that male friendships are being erased, while happily erasing possible platonic relationships between girls and boys because girls and boys cannot coexist without instantly falling in love and fucking. Friendship erasure seems to really only be an issue when its gay.
With hundreds of characters, main and background, being straight, you decide to have a temper tantrum about 2 (two!) characters possible being gay for eachother.
To which people may counter âButs its a king and a prince! They cant be gay! They need heirs!â
Which leads me to my next point.
The scandal of a homo relationship and the need of an heir (and easy solutions):
There are many possibilites to make this work, especially in a fantasy setting.
Leaning on reality, we have adoption, which is less favourable since its not their own blood.
Or surrogacy, like many homosexual pairings like to do in for example India. Gay and lesbian couples come together to make children while still enjoying their freedom to be with the person they love.
Advanced science. At some point humanity will reach a scientific level where they can make artificial children in artifical wombs, with sperm and eggs they make out of the dna of you and your partner.
Which can easily be translated into a fantasy setting, that not only has magic but also uses science, like in WoW.
Having children only ever seems to be a problem when it comes to gays.
You cant deny homosexal pairings their biological children while at the same time being ok with human females being dicked down by various creatures, creating humanX hybrids.
We cant even crossbreed with other primates.
Those humanX hybrids also only work with either magic, or science (dna adapting mutations and the like).
In a world where human(or other)X hybrids exist, people use portals, people turn into bears, birds cats, a world with spirits and all kind of magical creatures, beings, monsters, environments, two gays having biological children is an absolute none-issue.
Reminds me of the adventure time drama, where people complained, that lesbians cant have eachothers kids. In a world with all kinds of magical impossibilites going on, this is the hill some people want to die on.
Another example, Steven universe. A gem forming a womb out of light, and giving birth to a human gem hybrid is widely accepted. Because why not, its fantasy science.
So why not give gays the same acceptance.
Is race/species relevant?
A minor point I just wanted to mention. For some antishippers race/species may be an issue in this ship.
The human king of Stormwind marrying another race/species. Would that be a problem?
A scandal perhaps, and it wouldnt be easy, but it would help race relations in the long run imo.
Besides, this is somehow only an issue when its two guys.
I think its pretty safe to say if one of them was a girl it would be deemed a romantic tragedy and theyd be rooted for.
Another point I briefly want to touch upon is where people argue that the existence of the characters on their own is being neglected. Both characters on their own are interesting, but its the dynamic they have together that is much more intriguing, they compliment eachother, and its cute.
I just wanted to vent a little about this.
DISCLAIMER: I did no research for this post, ignorance is bliss.
Also I barely know the story of WoW, Im more of a level/gear grinding kind of player.

Note: As soon as the canon changes, if one of them gets a girlfriend or married, I will lose interest and stop posting about it.
