Can't forget what we don't know. Not like everyone on the server has Jraul info.
You don't need to load Jraul to know that hp and mana was drastically buffed in 2.5.
I think we are all saying it is probably ok to slightly nerf this item WHEN higher tier content comes into the picture. Robes are not going (or shouldn't) really make much of a difference when the new content is below the tier/difficulty of monsters that we are already fighting.
But really, everyone is talking about this nerf, when really we have no idea what kind of nerf it is (just reducing the AC to the same as custo bp for example will make it useless, damn shame for how hard they are to get. Even if resurgum has been insanely lucky in acquiring quite a few, in SV we have seen two in several years, one of which walked away)
On the flip side, if the t12 content in the new zone drops a BP, why should it be any better than custo BP? And also there are people who don't have robes and have been playing forever (looking at Zorr, among others). It's just not an item everyone gets, on a highly contested long respawn monster that drops one loot (and a weapon that rots a lot) and used to be and should still be hella rare.
When zone testing is done for this new zone you better take like dragonkin there for balancing, because if SV and resurgum don't steamroll it (robes or not) then something is wrong.
