I recently starting looking into forming a BiS list for challenge modes for hunters, when I bumped into an odd issue with a few pieces of gear.
Let it be known that all these screenshots are from inside a challenge mode (Mogu'Shan Palace, to be exact)
Starting with myself with no gear on:
I put on my belt
As you can see, I jump up from 216 agi to 1222. This is a difference of 1006 agi. On the belt, there is a total of 1130 agi inside the challenge mode. Not only is there a missing total of 124 agi, but I then looked into the Fetters of Death outside the raid (http://www.wowhead.com/item=86761) and I discovered that there is 56 more agi coming from somewhere.
I then compared my scaled down Fetters of Death to a 463 belt
From the tooltip, I'd gain +18 agi, not accounting for sockets. However, there is 2 more sockets you can gain over Bindburning Belt, which would (in theory) give you +320 agi. Would this bonus 302 agi not be insurmountable? And would that not mean that as we progress through tiers, challenge modes get progressively easier?
Which brings me to my next item I looked into, my helm. (http://www.wowhead.com/item=89820)
As you can see, I move from 216 agi into 1403. This is a difference of 1187 agi. From the tooltip, I read a total of 1352 agi gained from the helm. Again, we're missing 165 agi.
I thought, man, this sure is a lot of agi just from my helm, I don't believe that any 463 helms have this much agi. Comparing to a 463 helm:
Not only do I lose 217 agi if I was wearing a 463 helm, my secondary stats are borked too. 789 hit is changed into 634, and then the haste is bumped up from 357 to 512. Outside of the raid, the helm has 720 hit, 530 haste, and 906 agi. The Blizzard difference from the 489 helm to a 463 helm is 906->876 agi, 720->634 hit, and then 530->512 haste.
The point of this post is that I'm curious if these differences in gear are intentional, to gradually nerf gold challenge modes over time, or unintended, giving the option of potential exploitation of stronger pieces of gear.
These two pieces are the only two I've noticed so far, but I've only looked at around 6 pieces in total. I'll report back any more findings.
