Dear VoidStar, please don't post things like that, someone might read it and think you are actually right, because he've read it on Elitist Jerks which is the best source for game and class mechanics information.

First of all, Haste as Affliction is your best stat, other than Intellect and Spell Power, no matter you like it or not. Smarter than me and you people here have proved it long before. Reaching the extra DoT ticks thresholds comes naturally if you are gearing properly.

Second of all, having an extra tick on Drain Soul is not a waste, it means it will tick more often and the time between the ticks will be shorter. Quick example of how Haste Affects it, black on white - get Gnosis Casting Bar addon and check how many ticks on Drain Soul you have with Eradication and Heroism up before you need to cast Haunt. Then check how many ticks you normally have without any haste up. It's easier to see the difference.

How is that actually a "waste"?

Edit: Someone hinted me on a private message that you might mean that it's not worth to gem for haste and things like that, if so, your post doesn't really make it clear.

I guess you have missunderstood voidstar's thread which is rather clear.
He never state that haste is useless but that tweaking your char to reach haste treshold is not worthy. Some people still think that replace int gem by haste gem or choose haste enchant could be interesting to reach haste treshold.
Extra tick only allow you to save some gcd because you'll have to refresh your dot less often. Tick frequency is not influence by any treshold.
For DS,(15 sec dur, 5 tick every 3 sec) the first treshold is 9,990838 % which give you a tick speed of 2,727 sec.

However having 5 tick every 2,726 or 6 tick every 2,727 is not different in term of tick frequency. The only difference is that you'll have to recast DS less often since it would last 16,362 per cast for 6 tick instead of 13,63 per cast for 5 tick
The problem is that that you never channel your DS till the last tick because you have to refresh your haunt before. This make the extra-tick useless.
For affliction, only UA manualy refreshed has some benefit for the extra tick. However, the gain is smal cause. It only save a GCD every X UA. X is the number of tick. If UA tick 6 times, you'll gain 1 gcd every 6 UA .

So as VoidStar state: getting haste is good but sacrifying int for haste treshold is bad.

PS: VoidStar is according to me one of the smartest guy here which post regulary priceless hint and ideas.

I don't know where you are getting this idea that haste adds duration to dots/channels. It doesn't and it can be easily tested and proven if you'd take a few seconds to do so. You can do as I did if you have problems believing what you are reading.

Go to a dummy with all your affliction gear on. Cast drain soul, count the number of ticks and look at the duration of the channel. In my case it was 14.93s channel and 6 ticks. Now, take off all your gear and repeat the test. 15s duration, 5 ticks.

So obviously haste DOES affect the tick frequency and NOT the duration. Every tick does not occur at 2.727s. Now I'm not at all suggesting that someone gem for haste as affliction to reach a haste threshold. I'm just saying that your posts are inaccurate and could be very misleading to those that don't know any better.

Angelic had it right, I'm very confused as to where you're getting your ideas from.

VoidStar and thetrueavatar you are both wrong as stated by Angelic and Dondochakka, this is not how DoTs and haste work. Haste threasholds represent a big DPS increase since it adds a new tick without changing the duration of the DoT.

I was originally confused by this concept but it was cleared up for me nicely, so here's my trying to spread the wisdom:

Voidstar is correct in saying that reaching (or missing) haste threshold does not affect your DPS much.

Arguments for the importance of haste threshold claims that upon reaching a haste threshold and thereby gaining an extra tick, the frequency of the DoT ticks are increased. This leads to a DPS gain and is in fact true. However, while extra ticks have their thresholds, the frequency of the ticks does not, and is continually increasing based on haste.

The tick frequencies of DoTs are always affected by haste in a continual faction, not a spiky one in which you only gain an increase in tick frequency upon reaching the next haste threshold.

Hope that helps

Lets not forget that affliction mastery only affects affliction dots and not shadow bolt which makes haste even more important for affliction. There is simply not a scenario when you don't want to stack haste as affliction. This does not mean to gem for haste since int is still the best stat so you should still gem and enchant int but for gear its all about haste and there is plenty of it in firelands.

Edited for noobness.

Hello there. I'd like to ask for some assistance. I wanted to have a challenge and since I enjoy the Arcane Spec so much I want to try a PvP oriented spec with Arcane as it's base. I understand having a lot of resilience is a prerequisite for having it be effective. I'd like to hear your thoughts on how I should arrange the Talent Tree for this this undertaking.

Thanks for your time, any response would be appreciated.

I am not sure how the dps increase will work from class to class, but it seems that it works extremely well for mages judging by the following link:

World of Logs - Real Time Raid Analysis

I actualy care because im not able to kill him since cata came.
I remember to kill him many times at lv 80 just because our damage to the pet wasnt enought to kill him.

Now I even unequipe my weapons before getting MC but isnt enought, my pet dies.
This boss is tameable if anyone want to bypass him.

Why no1 doesnt take liberty of updating this thread? You can see stuff about 4.0.6 patch and useless stuff if it worths doing scorch anymore as main spell! It would be really nice if ppl posted usefull stuff like BiS lists and tips from comments so ppl dont have to read 24 pages of comments to check for updates.
