a bis equiped mm hunter with good rotation is able to do 42-48k dps in icc, fact
edit: and yes, mages are still better but: they arent the only high dps class, deal with it mr. i hate mages
So, going from what you're saying, a
level 80 Marksmanship hunter is pulling 42-48k dps inside icc?
Let's have a quick look at world of logs shall we?
Ignoring the Korean logs (which all seem to be from the same guild), we have the following for Marksmanship:
Marrowgar 25H: top is 60k, top 75% ends at 41k DPS. Our hunter (remember he's BiS geared, has a good rotation and is still level 80) is in the top 75% of all ranking hunters on 25H marrowgar. Pretty impressive, since 99% of these ranks are level 85 players.
Deathwhisper 25H: Top (again, non-korean) is 70k (Same guy as marrowgar), top 75% ends at 41.9k DPS. again, our hunter ranks in the top 75%, so up there with the top level 85s of the same class and spec.
Let's look at some of the more "patchwerk" fights in the instance.
Deathbringer saurfang 25H: top is 81k, and top 75% ends at 62k. If we dip to see where this 42-48k dps (expected top of this, because of the fight) lands, it's between the 120-200 mark, or the end ~40% of the top 200 raiding MM hunters who logged ICC. Again, pretty impressive, since the fight won't stay in Careful Aim range for long (unlike deathwhisper).
Festergut 25H: top is 68k (remember I'm ignoring the KR logs, as they all appear to be almost the same guild), and the top 75% ends at 49.6k DPS. top 50% ends at around 43.4k dps, which is around where our supposed hunter would be.
I'm just going to stop there, as there's next to no point continuing. Why is this? Because 42-48k dps from marksmanship is extremely outlandish. I could imagine the hunter might land at around 30k (perhaps 40k, just because MM will likely have 80%+ crit) or so with double rapid fire plus bloodlust lasting exactly the same length as the fight, or less.
So, in my typical condescending fashion, I'm going to say this: No, there aren't classes that can match mages in ICC. If there are, Marksmanship isn't one of them.
I can assume you'll probably see this post, not read it, and call me a noob because apparently I "can't play MM properly" or some other form of personal attack/rage. Heck, I've had it before, from others on this same board (I have a horrible habit of telling people exactly how and why they're wrong), so I'd suggest you just get over it.
Simple case in point is as follows. Unless the 5man group competing in the race has a mage, they honestly don't stand a chance of winning, just because of the massive disparity produced by scaling with crit and haste.
Secondaries are extremely powerful at this level (around 70% more powerful than they are at 85), which almost makes them
better point for point than spellpower. Because mages (fire particularly) scale extremely well with these secondary stats (as a lot of DoT classes do), they will be doing phenominally more dps than any other class, with maybe elemental/assassination close-ish to them. coupled with the fact that they don't lose much between 80 and 85 (flame/frostfire orb is a nice cooldown, but unless you're frost it doesn't provide a massive DPS increase), it just adds to the strength.
I could go on at this point, but is there any point? I've probably derailed the thread enough as it is.
