My issue with that is, that it’s depicted unrealistically.
Let me explain.
First logic flaw
In the shots we see the shoulder armor being put on, leather straps pulled and locked in. On the front side, that makes sense.
But who tightens the straps on her back? Because those are definitely there, otherwise the entire armor makes no sense whatsoever in design itself.
Second logic flaw
The Chest plate is put above her head, perfectly symmetrical in the downwards motion. But beforehand and afterwards, we see no one help her.
She has one arm, it is physically impossible to even put a T-Shirt on that easily alone, with one arm, without help.
So why should a plate armor that weighs at least 5-10kg be easier to pull on?
Third Logic Flaw
What is a Squire? Google says:
“The word ‘squire’ comes from the French word ‘escuyer’ meaning ‘shield-carrier’. The young squire learnt about how to be a knight by going with his master to war, carrying his shield, putting on his armour before the battle, looking after his horses .”
Faerin Lothar (the Paladin we speak of) is a Lamplighter, which definitely appears to be some sort of Knight order. Given she has her own custom armor, it is likely that she has a high-ranking status within her order, means therefore she is a Knight or higher.
She has no Squire, yet is depicted unrealistically in a way to be able to put on her armor alone, with one arm which is a major disability and while being blind on one side of her face which is another major disability.
It’s honestly worrying that Blizzard depicts a disabled character in a way that is anything but being realistically disabled, downplaying the actual handicap and how the struggles are in real life.
Almost like they put only half a minute effort into thinking this through. And all of those issues could have been solved by have 2 Knights with deep shadow below their helmets arm her.
Because people serving YOU, is STILL the biggest display of power. Because it recognizes Authority!
What comes next, a Dracthyr in a wheelchair? Oh… Wait… We already have that.

Think about for a second. A Dracthyr, a literal genetically created super soldier dragon race has one of them sit in a wheelchair, a prosthesis device for people unable to walk! That’s like having a person without arms being called a professional climber.
You can’t fight without legs to stand on! That’s just simple physics and combat knowledge.
Next Blizzard is going to tell me Pizza is best served cold and Ice Cream should always be hot! 
EDIT: Fourth Logic Flaw
When she puts on her coat, it just flaps down her back. But what about the cloak joints on front of her chest piece? You can’t fix those on easily with just one hand.
If you put it on first on the disabled side, you have difficulty putting on on the not-disabled side.
So, logically you put it on first on the not-disabled side, then pull the cloak pin up from below your disabled arm, over the shoulder and lock that part in its pin socket. Which then would result in your cloak not flapping downwards symmetrically, but actually being pulled up without a flap, asymmetrically.
So, this is another logic error, not in display, but animation.
