A reasonable compromise to keep it balanced might be to allow it to be resisted if you're the mob's current target, but unresistable if it is targeting something else. This would allow you to shed aggro before pulling, but once you pull you are in danger of a resist.

Just a thought.

Info on the MD Bug:

" This is a bug introduced with 2.1. Its very easy to reproduce. The bug is that only 2 out of the 3 shots will misdirect to your designated target. IF you shoot off the 3rd shot then ALL the aggro from the 3 total will go to the Hunter.

The only current workaround is for the hunter to shoot 2 times and stop, cancel the buff quickly, and resume DPS.

Try it on your pet. Shoot all 3 and watch the mob go right after you. Or, shoot twice and see it go to the pet." -Howitzer

"It's known and set to be resolved in a future patch, not all issues can be hotfixed." -Drysc

Ok actually YOU CAN refresh HM.
It does sound "casting failed" but HM got refreshed. No mana taken, stacks are saved. So you can refresh your own HM for free as long as you want without loosing stacks.

Another fun thing is with for example 2 hunters have 2 HM on target. Let hunter1 use rank3, shoot few shots (better stack it up to be sure), let hunter2 use rank4. Volia you have 2 of them and they are working (tested). Just both hunters need to refresh their mark from time to time (its free as above). So with 4 hunters you can have all 4 ranks of HM on target.

Wow...that has to be a bug. Do they create two separate, stacking buffs? Or does only one show up but both add to everyone's RAP?

Not to put too fine a point on how to exploit more efficiently, but killing him on the pull doesn't seem a good idea. Better imho to bring him to the raid at 5% hp or something, and kill him then, so the raid gets the regen buff.

Doesn't seem to work anymore - I've been aimed shotting them for 3k and they go to 1 hp and then lose damage from the mana shield. Has anyone had any luck making this work? We tried pyroblasting them and ambushing them with the same result as aimedshot.

I've tried aimed(critted for 3k), then FD, followed by steady-auto(shield was down, mind you). Still didn't work, they come with an inherent fail-safe now

The HM refresh is quite buggy in a way that it does not show that HM got refreshed + only hunter that used that HM can refresh it. You can only see that it got refreshed by debuff icon on target (when you however on it, it shows 'X time remaining').

For different HM ranks stacking, it is obviously a bug so use it while you can! You can have rank1/2/3 and 4 HM on target with 4 hunters and proper execution (h1 use r1, stack up, h2 use r2, stack up... + refresh). I believe that works for melee AP too (as long as hunters have 5/5) so melee dps will enjoy free AP too, 250 AP and 1000 RAP with 4 (dream on) or 185 AP and 740 RAP with 2 hunters.

The best I was doing was getting them to 1% as well, guess it wasn't just bad luck

If the hunters have a different number of points in imp. HM they stack as well. So lets say you have 6 hunters with 0, 1, 2, 3, 4, 5 points in imp HM, respectively. That's 6 x 440 = 2640 extra RAP on target. Now that's a lot of DPS.

Disclaimer: Only tested with two hunters (one with no points in imp. HM and one with 5).

Edit: Extrapolating this means you could possibly have 6 x 4 (number of ranks) = 24 HMs on one target. Someone has got to test this.

24 hunters, getting 10560 RAP each, and giving it back to the pets through scaling would really account for the word "Beast"Master.

I just wouldnt want to be the 25th raid member tank who tries to keep the aggro

Sadly, the benefit from the lower ranks is less so it would be something like 80 x 6 + 180 x 6 + 300 x 6 + 440 x 6 = 6000.

Little question about aggro and Mag adds. I was at Mag for the first time yesterday, so I dont know much about the adds, but I havent read anything about aggroloss.

Now on the first add there was a really good tank and his threat jumped as quick as I am only used to see it by bear tanks, so I am a LOT behind him in KTM, but I still manage to pull aggro every single time. So, there could have been some unkown aggroloss, but I tend to think that it was me, because I am always by far the top in damage AND I was actually the only one to pull aggro on several tries.

Now this would lead to the conclusion that the old KTM is somehow missing some of the newly aquired damage, maybe because of the hunters mark or because of Kill Command, which might mistakenly be put on the hunter by Blizz now.

If I would assume that it would mean that I am closer to the tank then I can see in KTM and it makes sense to pull aggro earlier then expected.

BUT I also threw in an unresisted FD in most tries, and STILL got the aggro of the tank shortly after as the only one. That destroyes the theory of missed damage in KTM, but also it cant be a simple aggro loss, because I was the lowest in the list after the FD.

Anyone experiencing similar things or am I dreaming?

Ragnaros, C'Thun, Murmur, Lurker?

Was main target set to Magtheridon?

I'd say you can raise any HM by 330RAP, so the only difference is the base, but thats an assumption, since on max rank each shot increases the RAP by 11, it might also be 10% of the base now that I think about it...
So yes, in any case its not 24x440.

Stacking HM got (hot?)fixed today, probably with other fixes. The way to refresh it is still the same: only hunter that used HM can refresh it, it is free (cost global cooldown) and it does not show any animation or anything.

going to bump this because despite a search of the thread i never saw it answered. i'm considering dropping engineering for enchanting after the lackluster changes in the patch if the enchant works. or maybe just for the +stats heh.

I wish I could drop Engineering. Unfortunately I was stupid enough to keep it long enough that no one else in my guild (and about 5 people on my server Hordeside) are actually high-end engineers. This means they rely on my for crit scopes, the new stamina gun, repair bots, etc. So I can't spec out of it for something more useful like, say, Leatherworking.

I'm hoping we'll see equivalent engineering recipes drop similar to what we're seeing for leatherworking (eventually.) Don't forget the engineering revamp isn't done yet.

It was answered somewhere I believe, but in any case it doesn't work. Wowheads ability description says specifically melee.

It definitely has a "+2" to the damage range on ranged attacks on my tooltip in game. So if it doesn't work the tooltip is bugged as well.
