Imo, it doesn’t make sense.
Logic wise, Holy Paladin should be strength. Yes, it’s a Healer, but it’s first and foremost a might soldier in the shining armor.
Same way Mistweaver Monk should be agility. It’s a healer, but first and foremost a quick martial artist.
Yap, this is weekend post
So let me get this straight, you believe Holy Paladins heal people by whacking them with all their might?
Works for vending machines, not for living beings.
Because to go to into Medical practice you have to go to Primary School, then Secondary school, do well there, then Sixth Form College, then do well there, then go to University and get your Degree, then pick a medical specialisation to excel at and do well there.
Can’t go far without Intellect at any stage of that process…
Maybe that’s just the UK…
I feel like being healed by a healer with strength main stat would be like getting ran over by an ambulance.
Pugilistic medical care.
"Oh Mah Gawds, I’m dying, my ribs are crushed, and I think I’m missing an eye, and one of my legs is hanging on by tatters…“Healer! Healer!”
“I’m here, wow, yeah, you’re really messed up, I’ll heal you.”
“Oh thank you! Thank you!”
Starts beating the heck out of the injured person, driving them into a Coma or more likely sudden Death
“Sometimes it is the only way to truly help someone that damaged” Walks away to sad music
Then have more to share strength weapons and trinkets? This is wrong xD
Then we have to create strength healing trinkets as well that only Hpala will be able to use?
Same goes for MW with agility.
So wrong 
because you need a very high iq to understand healing rotations
I don’t think a character like that could heal anyone, but I can imagine how his his battle resurrections, would look like:
*AngelPaladin flexes his muscles.
AngelPaladin proceeds to violently smash Shieldwarrior face, waking him up of his coma state.
Imagine not getting healed, but getting battle resurrections this way: all the time.
The Tank would be motivated to never die at any given time.
Cheers.
I would describe it more like Borderlands 1 type of healer.
I mean the state of ret, enhance and feral druid would beg to differ about needing intellect to heal this patch 
disgustingly healing for way too much for dps classes.
At the end of the day, the distinction between the stats means nothing anyway, they all do exactly the same thing, so you could easily just call it Power and be done with it.
I get it from a simplicity point of view, why always int, but it never sat well with me. Games like Everquest had a distinction between two Caster stats: Intellect and Wisdom. Wizards, Necromancers, Magicians, Enchanters, Shadow Knights would gain mana from gathering intellect, as well as mana Regen bonuses, but they gained only marginal amounts of the same when having Wisdom on gear.
Contrarily Clerics, Paladins, Druids, Rangers, Shaman and Beastlords gained primary benefit from Wisdom, and less from Intellect.
I liked that, if only for RPG reasons. When you get to the nitty gritty of WoW healing magic, it’s not an intellectual affair. Most of them heal through either sheer willpower, or some kind of spiritual understanding and knowledge. It doesn’t make much sense for intellect to be the stat that fuels them.
I mean, it’s ludicrous to me, to suggest that the primary stat of Arcane mages, their fuel, raw intelligence, given their discipline involves rigourous study and arcane/academic understanding, is precisely the same one an Orc soothsayer or Shaman requires to heal or harm. Doubly so when you consider shamanism as presented in WoW involves no logical study, no scholasticism, nothing like that. It’s purely based upon stuff you feel, sense and Intuit and folk wisdom which often runs contrary to logical understanding.
Guess it’s a peeve of mine. I like spirit being in the game because the idea healers need spirit as well as intelligence made sense, whereas warlocks and mages for example got marginally less benefit from spirit. I don’t like that as far as the game is concerned “intellect” is the thing all casters require no matter how disparate their disciplines are, or irrespective of whether one requires intellect at all (Monks, Priests and Shaman I’d argue require none. They can be clever, but it’s not like that’s key to accessing the powers involved) or you end up using such a vague notion of intellect ie “it refers to both logical understanding but also illogical intuition” you may as well not use the term at all.
Honestly the spirit they used to need made a bit more sense than Intellect. Strength should never be a thing though
Funnily enough, at this point they can just rename it primary stat because it doesn’t even matter anymore. It gives either attack power or spell power which both are obsolete as all of your spells take either one.
Retri pallys exorcism scaled for instance with spell power back in wrath, not that it made any difference at all, just meant that taking a specific talent point in retri spec was good and that 5/5 extra intellect in holy tree was good as int used to give spell crit (by the time ICC was out everything was undead so exorcism would automatically crit anyways - useful for RS though).
Then why is Homeopathy a thing?
Yeah it’s cool, but it ain’t gonna give you hitpoints back is it? 
Homeopathy is what you get when you tell resto shaman to favour int over spirit.
“This heals because water and science and diffusion and science”
Some classes were not meant to try and handle int.
More strength = stronger heals. Why dont you get it guys?
Next time I need medical attention I’ll go to the nearest gym.
The tank has taken some minor damage. The Paladin “healer” bonks him with his hammer and proudly proclaim “All better!”.
The rogue has taken some serious damage. The Paladin “healer” lifts his hammer over his head and then brings it down on the rogues face with all of his strenght.
The party stood in fire and took some damage. The Paladin “healer” starts to spin around like a madman. Swinging his battle hammer wildly in every direction. “Healing” friend and foe alike until there is only a red mist remaining.
