Expose Weakness has been missing since the Dragonstalker 8/8 days.
Reported as bug then, reported as bug when the PTR hit with the new and improved Survival talent trees, it's still there.

I answered your timing question in that thread. As for expose weakness:

http://www.thottbot.com/s34501

It has a spell school (Arcane) so it can probably be resisted. I suspect it works like Arcane shot and a full resist = miss.

No.
The old Dragonstalker 8/8 set bonus had issues with it being resisted at times. The effect was changed as to make it not resistable (check patch notes for exact quote).
The missing started when this was implemented - or, I neither experienced it or heard of anyone else experiencing it before this point in time.

I got to bring up the haste stuff again. While I was checking if I'd prefer the Mukoa Gloves over the T5 Gloves as a next upgrade my calculations gave quite a strange result and I'd like to hear if I did something wrong.

Without going into the well known formulas I picked a base of 2050 RAP, 33.5% crit and the sunfury bow, which leads to about 1147 dps for a BM without IAotH in a pure auto/steady rotation.
Now, would I have the same dps on a 2.7 speed weapon, this would give a large loss in autoshot damage per shot and at the same time give a large boost, because your hasted speed gets from 2.1 to about 2.0, so in combination it would be an upgrade of like 15dps.

Now, the new haste items give you that large boost, because the rotations gets better without losing out on autoshot damage because of the weaponspeed.

So, calculating that a haste item brings me from 2.1 speed to 2.0 speed while keeping the base of 2.9 that would lead to 1204dps, which is roughly the same as I would get from 200 RAP. Now I know the Mukoa Gloves do not bring the speed down to 2.0, its more like 2.03, but thats still an unbelievable upgrade or am I missing something?

I think your old links or pictures were a bit different, where crystalweave even had a slightly better result, but I am not exactly sure what you are trying to say now.
While I am a little bit confused for the moment why the crystalweave cloak is 10 itemlevels higher then the vengeance wrap, I dont understand why now suddenly 2.1 is the lowest possible speed.

I mean, everyone had a steelspine crossbow or even a wolfslayer, and I didnt see any problems with weaving in the steadys, so why would it get worse when you use a haste item to bring you to that speed with the sideeffect that even the steady shot is slightly faster?

You dont see a problem weaving shots, but the actual dps when you use rapid fire and stuff in real enviroment dont make those speeds worth it.

If you see what I mean.

1.5 GCD, 0.5 sec pushback effect + ping = 2.05-2.1 Depending on your connection.

possible that hes saying 2.1 because of trying to fit a kill command in?

said he was "using auto/steady + KC macro".. i feel with 2.17 autoshot with ~200ms i cant macro a kill command because of lag or atleast it looks like its being delayed in the quartz swing timer bar.


edit; nm, that makes sense actually and could describe why i cant fit a KC in. 1.5+0.5+0.200 (correct? 200ms) = 2.2

Do you also use your average steady shot cast speed there?

Ok, I forgot that you included the possible 0.5 seconds for kill command.
Well, then this would leave 2 questions:

1. Is it a gain or a loss to stay above 2.1 speed to get a perfect kill command once every 5 or 6 seconds in comparison to getting more dps out of the rotation and have it clip once every kill command?

2. Will there be a realistic (in terms of lag) point, where you would have enough haste to say you will not use kill command at all in favor of a perfect and tight rotation and still gain dps?

I'll do some WWS tests with just auto/steady today then, can use Wolfslayer with and without Crystalweave as well.

Will see then.

Massive brainfart in typing.

Well when under extreme haste effects (lust, RF, Imp Hawk) the best bet for thus far has been to abandon Steady altogether for the duration. I'll switch to Arcane, Multi, and KC as my skills as I can then still get my two shots out in 2.1 seconds even if it's just two autos since everything is on cooldown. (note I said extreme haste effects there) and sneaking in the arcanes and such is just bonus damage. Only relying on a Steady>Auto rotation means you'll just ignore how good haste can be even with the GCD.

Under normal conditions though, I'm trying to get my autos to under 2.0 with haste rating. I can still use KC then, but I'll only use it when I'm arcaning or multi-ing for ease of clipping avoidance.
