You may have talked about it a lot, or maybe you don't, but am I the only one who doesn't understand why DL has a BPD shield (Darkness Dragon Spirit) instead of a MPM one? Let's be honest, MPM shield > BPD shield in every aspect, we know that, and it should be considered when you balance the armor, I'm ok with that. What I don't get, is why DL doesn't have the MPM one, considerind that it is a Defensive armor (without artifacts) and usually the other "defensive" armors have MPM shield or MPM AND BPD shields, or have another special shield like "Shroud of the Undead" of Necromancer (if you don't know, it gives you +140 resistance of the last element that attacked you, meaning that the enemy attacks will heal you), but DL doesn't, it only has another shield (Earth Dragon Spirit) that in practice does the same that a BPD shield but worse, making the class lackluster as a defensive armor, mainly for 2 reasons:
1) You can't evade damage: Is the same problem that Riftwalker had before it's buff, there is not a single turn where you don't get damage (ignoring passive MPM, but you get that no matter the armor from your items) so even if is a little, you will get hurt, and you start to notice the damage the longer the fight is (and except that you are using the rage artifact, the fight will take some time), but hey, you have a good heal, so you should be ok, right? Kinda, if this were the only problem of having a BPD shield, I would be perfectly fine with it, but then it comes the second reason...
2) Crits and stuns/debuff bypass your defenses: And believe me, even if this is not that common, when it happens, you notice it very hard, if the enemy has a debuff or a stun, and that attack has a guaranteed crit, you have literally no way of evade it, you just can't, so hey, one of the most defensives armor of the game, if the enemy got some decent crit rate, gets destroyed. Just... Nice. And I'm not joking, if you have the house item for seasonals, go and try to fight Merged Alkriloth with DL, and tell me how you do... But getting back to the topic, the nukes (with guaranteed or almost guaranteed crits) and debuffs that have guaranteed crits melts DL, you can't do anything about it.
I know that this sounds like a rant, but I'm trying to be fair, and I feel that a lot of people is fine with it being BPD because they or either don't use the armor almost never, or when they use it, if for general questing, and don't test it where it matters, if you don't believe me, look paladin, that armor is a monster, is probably the best defensive armor of the game, and you wan't to know one of the reason for that? it's MPM shield, because even if you don't spam it, if the enemy has a nuke, stun, or charged attack that you can prevent, it's MPM DOES the work, when you use a BPD it just... Can't, so please, if you want to say that I'm wrong and that the armor is fine as it was, at least test it in those scenarios (aka bosses with high crit proc chance), and if you can, go and test it with Paladin or even Master SoulWeaver, if you can tell me that DL can do as good or even better than one of those armors... I will shut up. (Really, if you can go to Merged Akriloth and try to kill it with DL, just try it) Anyway, to finish, what I am trying to say is that BPD shield nerf the armor more than what some people believe, and giving it a MPM shield doesn't hurt anyone, but will help it a lot to be what it is intended to be. a defensive armor.
Side note: As you probably can see, English is not my native language, so there may be some (a lot) grammatical mistakes, and it may be hard to understand what I'm trying to say... I tried my best to explain mi point of view about this... But I will understand and also try to apologize if you can't read this post.
