Why would a barbarian wear Hide armor?
I told you ... bcs it looks good.

Have you seen Barbarian in any other armor? Ugh. :-/
12 + Dex (max 2)
Versus Unarmored Defense of 10 + Dex + Con.
*13 + Dex

But you could wear Scale or Half Plate or whatever other Medium Armor that provides better protection.
If you have it.

And that is exactly why i said they could adjust AC of Hide, to match Scale. >> Same protection, much better style. :P
Barbarians almost always have high Con.
This may come as a surprise to you ...
But Barbarians have as much Con as you (as their player) give them ... meaning anything between 8 and 15.

Sure they are "suppose to" ... but that is once again, different topic ...
There is nothing in the heaven, or hell, or anything in between forcing us to make effective characters. :P
As for boosting the AC. Sure. Why not?
Exactly ...
Since you are aginst it, i would like to hear at least single reason except "its not suppose to be that way".

Why not also include flying poodles in the game? Like in the movie UHF. "Today, we're going to teach poodles how to fly."
That is easy question.

Bcs its bullshit you just made up to dementate the argument ... cute effort, but its not going to work on me, so either react on asked question or spare yourself the awkwardness and simply ignore it.

Hide is low on purpose, Ragnarok, and it's made for druids on purpose.
Yes and that purpose is named "starting gear" ...
If you played DnD at least once i believe you heard about it ...
I also believe that you allready noticed that they "do not" start in Hide armor in this game ... so that purpose is void.
I also believe that you allready noticed that while hide armor "properly provides" 12AC ... several armors in this game provide exactly same protection while not limiting Dex bonus:

And they all are very easily accesible for player ... so why exactly would any player wear Hide Armor "purposely created for his druid" instead of litteraly any other from this list?

Note that except Leather Armour +1, wich is sold by FIRST VENDOR YOU MEET they all are obtained by simply picking container.

So the question stands ... what purpose is left for Hide armor in THIS GAME (read again THIS GAME, meaning NOT TABLETOP DnD ... read again NOT TABLETOP DnD) ?
Give druids the ability to wear armor like scale and half plate and you make things like Hide worthless.
Open your eyes, hide IS worthless right now.

Am I gonna cry if they chuck Hide? Nope.
But you will if they make it actualy usefull?
