"Class Addition Requests
Contrary to common belief, there are in fact items that do not correspond to the common class combinations, or that can only be used by one or two similar classes, and are actually supposed to be that way. So unless you have a better argument for why an item should be <my class> usable than "This here other class that shares armor type/casting stat with mine can use it and I can't!" please do not post a request to have your class added to it. If you do post without a good argument for your class to be added to it, the post will be trashcanned."
I agree that Ranger being on this item would be nice. So I will try to take a stab at making an argument to put RNG on this item.
I am not sure if it is simply a problem with rangers but shoulders are a very hard slot to upgrade.
Looking at the Top 5 ranger list (lolz):
2 of the top 5 rangers in the game are using Blood Mist Amice that are T9 shoulders from early Tower of Tarhyl. The rangers on this list are very well geared in almost any other slot. There is no reason why an item should last 3-4 tiers of raiding especial one as mediocre as this.
The other 3 are rocking Shoulderpads of Decaying Matter from early Spires of Saitha. Unlike the item noted above this is around the correct tier for their over all gear. However, the item seems to be more so geared for a healer time class despite the item being all/all and it is rather lackluster for a ranger.
Currently the "best" ranger shoulders in the game are:
Epaulets of the Inexorable Dream OR Dhuro, Conceal of the Assassin
The Mistborn shoulders for their teir are simply amazing. They also have AE7 helping rangers do more DPS with their Runic 1. If you're killing Gloom however they should start to feel a bit dated. I feel that these shoulders seem so great because there is a lack in shoulder slot items for melee/ranger DPS.
Dhuro, Conceal of the Assassin are also simply amazing shoulders. However since they have bane damage on them they tend to go to the four other melee that can use them first because rangers bows do not benefit from bane damage.
