Not 100% related to rogues:

At some point, the Frag Belt engineer tinker was improved and currently does 36000 average damage on a 1 minute cooldown with an instant. This should provide a minimum of 600 DPS if used on cooldown, a bit more with crit, and more still if there are multiple targets to hit.

The question is, does it reset swing timers?

I'm also curious about this. My raid leader asked me to swap from nitro to belt for extra DPS on some heroic pushes. I did but was hesitant because I thought there was a swing timer reset.

If someone could explain how to test for this I would be happy to provide logs for analysis.

I'm pretty sure Wound Poison is never a DPS increase in PvE anymore. The major mechanical change in Mists is that Deadly Poison no longer has stacks, and so immediately upon first application, you get additional damage every time it procs. In Cata, until DP was fully stacked, you didn't get the extra IP procs on application. As that ramp-up time is no longer an issue, DP is likely to do more damage than Wound right from the first application.

Has anyone had any success using Growl to taunt the Amber Monstrosity in Amber Shaper heroic? From experiences with Tsulong hc my guess it that it just won't taunt off as it should but if anyone knows for sure that it works on the Monstrosity in Amber Shaper hc please confirm. The idea being to take the Fling instead of the tank (so taunt just before Fling - get flung and tank stays where he was)

I'm not sure if this has been discussed anywhere... I noticed that a 5cp Rupture can be trumped and replace by a 1CP rupture. I didn't think this was right because it was happening to me a lot and I felt that I was wasting CP's and dps. I submitted a sugestion to have it fixed and also a trouble ticket to see if I could get a follow up on the suggestion. I was immediately within seconds wispered by a GM to explain my ticket. So I ran to a training dummy, built up 5cps, ruptued, then gained a CP giving me 1, ruptured again and the 5CP..25sec or so rupture was replace by the 1CP..8sec or so rupture. The GM said he was watching and understood what I was talking about. I just feel that they should make a "There is a more power spell already active" to fix it. The GM then submitted a bug report on my behalf. I, for one, hope they fix this issue. I'm just posting here to ask if anyone else has noticed this and think it's a problem.

Yes it is a known issue to me. Just don't mash the button like your life depends on it and you shouldn't really have an issue with it.

Rupture used to work the way you are wishing it did, but they decided to fix this (or maybe break it in your opinion) so that it was possible to refresh rupture early (between the last and second to last ticks) without losing a tick. Honestly, this is a better place for rupture to be as far as refreshing and keeping as close to 100% uptime as possible goes. As the poster above me already mentioned, my suggestion is to not mash buttons. Let us all hope they don't act upon your ticket and revert rupture as it would be a large quality of life decrease for most of us.

Technically: I'm sure it's possible. Will they do it: extremely hard to say for certain. They'll have to see some true benefit in it, especially mid-expansion

I doubt they'd specifically put in different refresh mechanics based on size, but they could, for instance, prevent replacing a longer buff with a shorter one, which would solve this problem in most cases.

That's exactly how Slice and Dice and Recuperate work nowadays. Should help us make fewer mistakes, however rare they are.

There were times (but I think that was pre cata) when the duration didn't matter but the damage the dot dealt, which was rather annoying because you were unable to refresh something until it completely wore off.
Though the current behaviour is all in all probably the best everyone could hope for (in most situations) just for the added flexibility.
