*Hold the line and jump*
To begin with, and to calm down everyone, we actual 2h guard change not gonna stay in its actual state.
Lot of passionate discussions around this radical test and finally some propositions here and there.
I never hid that I was not a theorycrafter, but these recent exchange point to me some details i didn't knew (and seems lot of ppl don't know too).
When it come to damages from guard, all damages are converted as melee damages. Which mean, even if a BW hit the guarded target, the damage from guard are converted on melee damages. This point heckle me.
Reading guard description of the ability, first line says :

"You defend one of your groupmates and try to take attacks meant for them". Implying, your body becomes his shield you try to intercept damages before he receive them, not "you remove part of damages when it is too late" .
Ofc it is just a description. From original client, and it doesn't mean it is supposed to work like this.
Some have tried to explore the client to try to understand how it was done. before reading further, some hardcore aprt are obviously parts are missing to confirm 100% the general idea, but according the understanding of abilities a guard should have been designed like this :
"When i hit X who is guarded by Y. X and Y take the same attack with 50%, but it will affect Y only if X takes damages."
Ofc, this is not what happening actually, and from some memories, this is not what happened on Live too, and i'm not gonna say the opposite.
Point is, i don't undestand the reasoning behind this sudden damage conversion when we talk about damage from guard, and i wonder what would happen if these attacks were prevserving their nature (basing my argument on description of the ability itself).
On a second point, does it mean that undefendable damages if they are divided (no idea haven't tested) are converted too ?
To summarize (tell me if i mistaken something, maybe forgot dodge here and there):
And if we were taking account of nature of the attack :
Now theory crafters, what would imply this change (admitting 50% guard is reverted)?
(As a reminder, stay cool. We are discussing)
