This seems highly unlikely simply based on game mechanics.

Shield of Darkness specifically states it is an aura which absorbs Arcane, Fire, Frost, Holy, Nature, Physical, Shadow. As the other twin does not have the aura, it would not be absorbing the damage. Shield of Lights is the same.

If you are not hitting the unit which has the aura, you are not ablating the shield.

Blade flurry procs once per main hand hit of fan (edit: mechanics may be different for the npc rogue, but afaik this is how it works for pc rogues). If you were, by some freak chance, the only person in flurry range while 17 people were in fan range, then every hit of bf would be focused on you.

The NPC rogue did have Blade Flurry up during that time. Specifically, the rogues FoK hit you, Chatown, Lefeinish, 7 Venimous Snakes, 7 Vipers and 2 treants and since you were the only thing left alive in melee range you got all of the Blade Flurry procs.

It would appear that you got gib'd by what PvE raid rogues have been using to gib trash. I'd suggest you stay away from the hunters using snake traps in the future as it seems to be one hell of a liability when the rogue is around.

Common sense would suggest that, however not all game mechanics fit common sense. Moreover, it may be a side effect of their shared health and there are only a handful of examples of that mechanic in the game so it isn't terribly well-studied, let alone the many inconsistencies that have plagued absorb mechanics in the past.

In this scenario, either Lightbane's health drops and ablates the shield at the same time (net 50% dmg boost) or her health stays the same, but that leaves an hp difference which would need to be normalized again (and again, etc) effectively double the damage dealt to her -- in other words, another 50% damage boost.

On the other hand, it could operate differently (replicate damage dealt to one twin to the other twin). I say this because even with the damage buffs I don't quite buy that our 25 raid dealt over 56million damage in just over 300 seconds (almost 200k dps or 8k dps person, including healers).

In either case, 50% of your total dps is being sent to other twin, and if that damage ablates the shield in any way it's guaranteed to be a net gain of 50% to attack the unshielded target, and possibly a 50% dps loss to attack the shielded one (absorbed damage not being replicated).

This shield issue should be fairly trivial to test. Let a shield come out, blow all dps on the unshielded target and see if the shield ever goes down. If it is in fact a damage increase there should be no real issue of destroying the shield. I guess we can give it a shot tonight.

I do kinda doubt it since it doesn't take an unreasonable amount of damage to destroy the shield without switching colors so if this method DOES work it will certainly trivialize that aspect of the fight.

Update:

We did 10 man normal ToC and it certainly seemed like we could dps the OTHER target and the shield still died. We tried this on 25 man heroic and could not replicate it.

Now on heroic it was a dark shield which we generally had trouble burning down. However, if the theory that you could dps the OTHER twin to take out the shield was true, the dark shield should have been JUST as easy as the light shield to kill using the "stay on the twin opposite your color" strategy.

Since we only did it once on 10 man (since we killed them) its possible that incidental AoE or people actually targetting the shield are what took it down. Another conclusion could be that it depends on WHEN their health tries to get normalized meaning it wont be consistent. A final thought is that it only works on 10 man and not 25 man but that seems like a very outside chance, at best.

I'm tending to side with the "it doesn't work at all and someone in my 10 man fucked up" explanation though.

Does anyone know if Improved Kick actually silences for 2s in 25 heroic faction champions?

Our rogues are throwing spec, but still seem to be having trouble locking down the healers... That 2s of silence would probably make a huge difference if it actually works. It seems as if that would be one of the mechanics that blizzard decided to make them immune to, though.

Quick modification to the parses, it seems that when the damage done to both bosses is added up it reaches indeed the 1.3 - 1.4 million mark the shields are supposed to have (i think). Tho the shield only seems to break if at least 800k - 1000k damage have been done to the originally shielded boss. Either we were very bad at switching or my script is bugged, but sometimes we deal 8 million to the unshielded boss and 600k to the shielded one and we fail the interrupt. If someone more skilled in perl then me wants to take a look at the script feel free to pm me

Unimproved kick locks out the school from which the healing spell is cast for 5 seconds. Nothing about improved kick can extend that time.

Point is, if the silence effect from improved kick is working, you can kick preemptively and just silence. This helps against instant casts, also.

Well, someone would have to confirm this who still has the talent, which was generally worthless otherwise.

When I >used< to have Improved Kick, I don't recall the silence taking effect unless the kick actually worked to stop a spell. And, regardless, it's still unclear why 2 seconds of pre-emption would exceed 5 seconds of the healing school being locked out even if you can pre-emptively silence.

Someone can confirm either way.

It should be noted that the instants people care about are generally druid HoTs which are easily dispelled and perhaps the priest fear, which is cast rarely due to the long cooldown. I still don't see any scenarios where you want rogues to respec to get this talent.
