how many tanks do u have in ToC 25? cuz u really need 3 tanks so that u get no more than 2 de-buffs.
ur specs not 2 bad but i would take points off Icy Reach, chilblains and deathchill, cuz for a tank u dont really need em.
Icy Touch might be good if ur off tankin 2 get the adds that are after some 1 else, but u got dark command and death grip for that, Chilblains u dont really need because mobs wont be movin round much anyway notso its not really that important and deathchill while it is really usefull its just not a nacessity, id put the points on acclimation and morbidity, extra defence agent magic is always gd, and the more ur hit the better ur defence is agenst that type of magic, cuz it stacks up 2 3 times, while it only gives u a 30% chance its great on bosses that casts beams or flames like in mimiron, ony and the worms in ToC 10 n 25, Morbidity is great, it reduces the time on death n decay u should really try n use this more often, its one of the best aggro abilitys a DK has, and the best way 2 start a fight off.
id also change ur Glyphs, id put in Glyph of death n decay, adds 20% extra damage, which adds more tps to it, Glyph of unbreakable armor which i believe is a must for any frost tank since blizz nerfed this in the last patch and Glyph of Disease, this saves the use of a rune and refreshes the diseases on all adds around u as well as ur target, plus i think this gives u just as much aggro as IT and PS do anyway, like i sed i think im not to sure on that.
also while frost gives u the best migration that just means ur ok alround, so on bosses n adds n what ever else u want to use it for, while blood gives u the best suvival, while its not as gd on multipal targets like frost is, altho it can still hold its own, it is the best agenst bosses, it has great threat and like i sed best suvivalbility. i would recommend u atleast try blood tankin out, i use to think the same as u that blood wasnt much gd for tankin till i tried it, it takes awhile to get use to, specally if u used frost from the start like i did but it is the best agenst bosses, have a look at my spec, while its prob not the best out there, i find it best for me, also have a look at Skeleton Jack i always us it for all my DK needs.
im havin the same prob with my hit rating atm, iv also concidered usin my dps trinket, atm tho my threat is ok so i dont really need it, thats y iv stuck with my tanking 1s, but if u do use ur dps trink id swap it with the ony 1, i think its a crap trink myself for the item lvl it is, ur way over def cap so its not like u need the def u get off it, and parry really isnt as good as what dodge is for DK tanks, and the only other thing u get is +15 fire resist, which u wont really need for most places cuz 1 u got anti magic shell which is great agenst magic. n 2, most of the raids u do will most likely have a pally in it n they have fire resist aura that they can use where ever u need it, so u dont really the extra resist u get off the trink.
i dont have a clue about KM and rime, they are gd for threat tho.
also how do u set up rune strike in ur macro so its used every time its up?
cuz im always havin 2 look n c if i can use it then press the button, but i keep missin it every now n then.
