If you bothered to read the Topic discussion , you would already seen it , but surely you didn't :

I read this every single time in all official and unofficial forums and everywhere.
How about if you were clearly wrong and what if reality is completely different than you could possible imagine ?
How do you get such conclusions that 4 HM can't be done as Protection Paladin?
Did you knew that Vanilla was never ever fully explored, neither people didn't ever use theorycraft about it?
How would you feel , if you were 100% wrong , because you couldn't manage to discover it or accept it?
Four Horsement and how to do it as Protection Paladin :
Let me Begin:
1- The most easiest of them is either the Shadow (top left) or Holy (top right) Horse .
2- You as a Paladin , using BiS Gear, all consumes and world Buffs , can manage to grow and have up to 14k HP or more.
3- Which mean , you are now able to tank (with some efforts) and handle 8 Debuffs from the horse.
How the Rotation and strategy work :
4- You can do it together with 1 Tank (it will be hard for Healers, but doable) Warrior or Druid , who is able to Taunt, one of the Top 2 horses as 2 Tanks swapping eachother (hardmode), since their normal damage is weak but the debuffs are only strong dmg taken.
5- First you as Paladin go there and Tank up to 6 debuffs (each of them reduce threats) and burn the whole mana trying to build massive amount of threats (exorcism ftw).
6- Once you get 6 debuffs, the Warrior runs and Taunt it from you (same rule by debuffs apply to him) , while he should make extra tiny or small amount of threats in order to take and just keep the target from you ,afterward he should not do any threats,but enough to keep the horse on him without making more than 110% threats compare to Paladin (it is called control over threats).
7- Once the Warrior goes up to 7 Debuffs (exact time when the Paladin debuffs are about to gone) he uses Last Stand or Shield Wall , so he can manage to survive the 8th without causing problem to healer, for the last debuff he simply not making any threats at all , so he is going to loose his target to the 2nd tanks (paladin) without any taunt used.
8- Once the last debuff hit the Warrior , thanks to aggro reducing by each mark , the Warrior is going to loose his threats and the Horse will automatically run back to the previous Tank (Paladin) who will be taking over from the Warrior with Exorcism and Judgement.
9- The Paladin then , can manage to tank up to 8 Debuffs with all cd's and Priest Bubble on him in order to Absorb and Survive the last one.
10- And vise versa with Warrior taking over at the end.
(challenging,but doable,never impossible)
11- Until the second time Paladin take over up to 8 debuffs (building up massive threats), the group already had like nearly 3 minutes spend, by that time , they should already killed one of the horses , which mean , you have extra tanks that are going to make it easy and take over this Horse too for lesser debuffs.
12- The Healers threats in this case it will never be any problem , since they constantly loose their threats by swapping and get the first 4 debuffs .
13- The only Place , this might not work is Private Servers , if they don't have this properly scripted.
