So, went on there and tested, Cobra shot hits a truckload harder than arcane shot (29279 average vs 20622 average). On the other hand, A cobra shot takes 1.89 seconds to fire, while an Arcane shot takes 1 second - which means that Arcane shot still edges out Cobra shot in both mobility, and DPS. If your focus bar is full and it won't affect Explo shot and Black Arrow, just fire away.
Here's a overview of the DMG spread and the dps (few notes - reforge is bugged ATM, the client crashes if you as much as try to put an item in the reforge window, which means that I'm running in full PvP gear, no gems, 6.38% hit and 4.74% expertise - AKA, being able to reforge I'd easily gain another 5K dps through not actually missing/getting dodged -.-) - note that I also did not use Stampede, cos I'm tired as fuck (won't include it for the other's either, cba redoing):
As for Marksmanship, it's clearly far behind - dummy tests are never a good indication because it has Careful Aim, but even with that playing in it's favor, it's behind Survival's damage (note: I did not hardcast aimed shot, as that is a playstyle that Blizzard has tried to shoo us away from for a long time, and Careful Aim would fuck up the result, so Arcane-dump):
(note: Powershot did 280K dmg over 5 shots, not included here).
Same handicap as Surv, no Stampede/not hit or expertise capped.
BM did less than the two (but probably does slightly better than MM, if you do not consider Careful Aim) - priorities was to use focus fire when it hit 5 stacks, KC on CD, and not overcapping focus:
No idea why the numbers doesn't add up (according to the dmg overview of all my pets, I do 45931 dps, but when I merge them, 42166?).
Gear stats, just to get it out of the way:
Make of it what you want, I know for a fact I'm able to push the limits of what's capable DPS-wise. Remember that in the raid, I had multiple raid buffs (such as haste, 5% agility, 5% crit, etc, etc), my gear was scaled up to a 496 Ilvl (up from 480), which also resulted in being *almost* hit/expertise capped, and I was using my old 4 set which gave me more focus and the haste procs (T13) because it scales up aswell
.
Yes, I'm quite sure, unless my recount was out of whack. Once again, we only managed to burn 50M hp off of the boss, so I spent about 30 seconds out of 2 minutes under cooldowns, so 100-110K might be more reliable.
Sure, but looking at those 3 logs in specific,
The Surv kill was achieved 5-3-2012 (at that point, I had done 12 previous Ultraxion HC kills as surv).
The MM kill was achieved 4-4-2012 (before I got a vial, too).
The BM kill was achieved 5-10-2012 (a week after the surv kill).
None of those dates are affected by being there "early" - the earliest rank is from MM, and at that point, about 1450 guilds had killed Ultraxion Heroic. I do see your point, but I'm not stupid enough to think that the ranks I get from week 1 through 4 are actually meaningfull.
