Honestly, I’d take anything, a Priest 4th spec giving 1h and shields/off hands or staffs that’s pure holy dps I’d take!!.
It’s major cool-down being Lights Embrace, becoming an avatar of holy fire empowering you would be visually amazing. Turning into a avatar of the Light!.
I don’t feel like bows are a Paladin thing, and I think you would be hard-pressed to find any other game, video or tabletop, where a Paladin would use something like that. Generally speaking, that would be something more geared toward a Warrior or Rogue or Ranger (Hunter in the case of WoW). There are even games where Paladins/Clerics don’t even use any weapon with an edge. Blunt weapons only.
I think if they did a 4th spec for Priest, this would be the most likely thing to do, but then I’m not sure what they would do for Paladin that wouldn’t look similar.
Paladins could get a Ranged bow wielding spec, Holy/Celestial Ranger type deal, focusing in Holy Arrow spells, it’s major cool-down could be Heavens Fury, where for “X” seconds Holy arrows rain from the heavens onto your target in a AoE granting Holy Power, which then can be used for your other skills.
Warriors with vrykul stance .i mean when you go in vrykul stance your character turns in vrykul would be cool 
I kinda like this idea actually. That would sort of make sense. Almost reminds me of Eric from the old Dungeons and Dragons cartoon with his magic bow with arrows that came out of nowhere (technically he was a Ranger, but I could see this bow looking like that).
The bow could have an xmog where it materialises in your hand when you draw it out of pure holy powers!
I will admit, 90% of the reason I want this spec is because of the light arrows from Zelda. Another reason I want it is because the combo of paladins and bows is so rare. I think that on some level people see ranged weapons as “dishonourable” and thus not fit for a knight in shining armour to wield. Personally I like the idea that being good does not mean you act like an idiot and charge into the dragon’s mouth. Empowering arrows with holy power and raining judgment down on the monsters (especially when they’re 10 times your size) seems like the smart option.
This is the reason I don’t think you would ever see that. Paladins/Clerics are just written a different way, to be “honorable” at all times. Yeah, using a ranged weapon for a wielder of the Light like that wouldn’t be seen in a positive light.
Is hitting people with magic blasts or throwing magic hammers at people really more honourable than shooting magic arrows at them?
Is the idea of being a ranged combatant seen as cowardly or is there something about the bow itself that makes it seem worse?
It’s always the mage and hunter players
You missed the point I was making of edged weapons vs blunt weapons. In D&D, there is a specific part when describing Clerics where they don’t use edged weapons because of the way they draw blood. Apparently, it’s better to bludgeon someone to death rather than exsanguinate them. 
The bar has become so drastically low for Blizzard, I’m not even asking for specifics. Just asking “please make a game that doesn’t suck anymore”.
Make demon hunters a heals spec with souls of demons or the dead in general they could come up with something fancy for that no doubt. Question is if they did make a demon hunter heal spec who’d play it.
Big difference in something cosmetic like green fire and a whole playable spec. People would lose their minds.
Paladins in WoW already have swords, axes and spears as available weapons. Priests also have daggers. In WoW edged weapons don’t seem to be an issue.
The whole “clerics don’t use sharp weapons” is a myth that came from medieval drawings often showing monks going into battle with maces. Since smashing someone’s face in with a mace will draw blood just as surely as stabbing them it’s unlikely that blood was the reason for their choice of weaponry. The more likely explanation is that maces are easier to use without training when compared to swords.
It was explained exactly like that though. It came from a much older version of the rulebook. I’m old AF, so I’ve been a gamer for a LONG time.
Since WoW modeled their Paladin on this idea, the idea of them using a bow or another ranged weapon is still probably well outside of their idea of what a Paladin should be.
I’m aware. I’m also aware that they don’t use ranged weapons like bows or the old “thrown knives” as Rogues had. That alone should be enough of a reason not to include them. The idea posed above could skirt around that though. A physical ranged weapon wouldn’t be used but a magical one made of Light could fill in quite nicely and I don’t think anyone would be opposed to that.
No
What if… both?
Add a fourth spec (third for DH and none for Druid) to current classes and also add Necromancers, Tinkerer and Bard to start? 
Sure this sounds good, but Blizzard isn’t capable of adding a 4th spec to all existing classes.
