Just quick note on the Fire Res Gear set. Don't forget to add the fire resistance on cloak enchant to the list. It's called "Enchant Cloak - Greater Fire Resistance" and gives 15 FR to the back-piece which I think is the best you get get for that slott in a fire resistance set.
Secondly, having the
[Battleworn Tuskguard] is quite awesome with the FR enchant nice it's changes in Patch 2.4. Comparing this helm with the
[Flamebane Helm]:
Gain
+ 425 Armor
+ 41 Stam
+ 40 Def. rating
+ 23 Dodge rating
+ 51 BV
Lose
- 40 Fire resistance
Both offer high flexibility with the three gem slots so I'll disregard that here. I would probably place the +6 stamina bonus you can get from the Tuskguard higher than +4 hit rating however.
The 40FR is of course a very valuable stat, but still, on Illidan you want to achieve crit. immunity against the mobs there. Even at the FR and crit cap you will take a beating. Stamina is also very welcome to have. This put's very high demands on your remaining gear to compensate for these lost stats.
Two items I've found post killing illidan are:
1. [Signet of Eternal Life]
2. [Cloak of Blade Turning]
These give you a total of 59 resilience rating and lower the defence cap needed to 453. This equals 90 defence rating for the pure "crit immunity", yet will of course offer zero avoidance. Still, the items are of high level and also have high stamina witch is good for the Illidan fight.
Basically you want to look at the given slot and what is best for that one. Chest - 150 HP, 15 defence or 8 FR. Well since you can compare this to say the cloak where only can get 12 defence yet 15 FR, having FR on the chest is quite a stupid move to make. Here I'd choose defence or HP if you can reach the defence cap in another manner.
Puzzling the pieces right for you set makes quite a difference. I've got around 20K HP buffed in my FR gear which is more than needed, but it helps. I would personally avoid the
[Flamebane Helm] since I get see it fit in very well with out gimping other stats.
In my current set, swapping that and this chaning gear around to compensate for what I loose and gain with it I'd be seeing:
Gains
+ 2 dodge
+ 2 FR
+ 41 hit
Loses
- 425 Armor
- 27 stam
- 7 def
- 51 BV
Probably more threat but less survivability, thus nothing really I'd want to do.
Edit: Seems you forgot to mention the
[Amulet of the Torn-heart]. It's a quest reward I think where there also is a JC cratable one very much like the ones used for Nature and Frost resistance. Also killing Maggie gives you the
[Phoenix-fire Band] which is very useful also. Someone else pointed that out but it's worth repeating.
The epic resistance shield
[The Fel Barrier] I think has little use in the FR set seing a piece like
[Kaz'rogal's Hardened Heart] bring much more stats to the given slott. This became quite a long note
