I've been thinking for quite some time about what items to get from ulduar and what items are best in slot, also been checking dk subforum but i haven't seen that anyone made it, so I decided to.
Main reason why I am making this topic is to help people who don't know what to take, and also hear some constructive criticism from other people who know dk class, maybe and better players than me.
Helm: http://wotlk.openwow.com/item=45472 - reason for picking this helm is because i compared it to other helm, this one: http://wotlk.openwow.com/item=45107 and since i use spec with bladed armor, 239 helm gives u more armor, strength and critical by nearly whole 2% so imo its way better.
Necklase: http://wotlk.openwow.com/item=46040 -i was checking all loot from ulduar and this seems to be only strength necklase with gem slot with perfect stats, there is another one but it has no gem slot, obviously this is better.
Shoulders: http://wotlk.openwow.com/item=46117 tier shoulders, you need it to be able to get 4p.
Cloak: http://wotlk.openwow.com/item=54803 - i've been thinking about what to get here, and i compared this cloak from midsummer event with algalon quest reward cloak, but this one is better because u will lose 1.6% haste if you take ring that gives expertise/crit instead the ones you'll see in this topic.
Chest: http://wotlk.openwow.com/item=46111 -tier chest ofcourse.
Bracers: http://wotlk.openwow.com/item=45663
Gloves: http://wotlk.openwow.com/item=46113
Belt: http://wotlk.openwow.com/item=45241
Pants: http://wotlk.openwow.com/item=46116 - there are other 239 ilvl pants http://wotlk.openwow.com/item=45134 but, since helm from tier has armor penetration, maybe u wont like what i will say, but armor penetration is almost wasted stat because with this gear you won't go for it, and some armor pene would be useless, instead of tier helm with arp, helm that i linked gives hit (noone likes when pestilence miss or icy touch).
Boots: http://wotlk.openwow.com/item=45599
Ring 1: http://wotlk.openwow.com/item=45534
Ring 2: http://wotlk.openwow.com/item=45250 -this is what i talked about when i linked cloak, in ulduar for dk haste is still supposed to be the best secondary stat, over crit.
Trinket 1: http://wotlk.openwow.com/item=45609
Trinket 2: http://wotlk.openwow.com/item=42987
Sigil: http://wotlk.openwow.com/item=40207 -this is still supposed to be the best sigil, especialy now that 4p gives obliterate dmg increase.
Weapon 1: http://wotlk.openwow.com/item=46097
Weapon 2: http://wotlk.openwow.com/item=46097
I've chosen this gear considering strength as main stat and haste secondary best stat for now.
And untill we are able to get midsummer event cloak, i'd go for algalon 10 man quest cloak reward http://wotlk.openwow.com/item=46320 and http://wotlk.openwow.com/item=45469 instead of haste ring.
These are your total stats with Horn of Winter with this gear (all str gems and 1 prismatic): http://i.imgur.com/CnUFYj4.jpg
