Void Ark to drop Esoteric parts for upgrade why?

If you're currently working on, but can't beat, A3S, you'll gain access to i120 head, body, and legs with 3.1.

Three out of the twelve equipment slots.

I would have rather had the fight been more reasonably tuned so that my group could have already cleared it despite trying for several months in a row by this point.
I think it's hard to overstate how much of a spike in difficulty A3S is compared to A2S. That's the problem I have, and that problem contributes to why I am upset about the situation.

I couldn't disagree more, A3S is one of the best designed fights since T9, it mixes things up from phase to phase making the fight interesting, as opposed to say T13 in which all of the phases were similar. It just requires a lot of attention from all 8 party members and a considerable amount of raid awareness.

The disagreement is mutual. I feel that it is easily the worst designed fight I've seen in an MMORPG. It's difficult for all the wrong reasons, and the spike in difficulty from the previous 2 encounters compounds on this.
