I am a shadow priest and i love it, but is it any good at 70 i see some many threads and crap i jsut dont know so if some can just tell me here that would be awsome thanks

Yes, Shadow Priests are useful in high end raids because of the mana returned as well as the casting debuffs they put on mobs (5% more spell damage and additional shadow damage).  Almost all 25-man raids run with at least one, some run with as many as 3 (though I think 3 is definitely overkill).

Yes, they have very high raid utility and idd also stacks some very usefull debufs on targets. Unfortunatly they dont do as good dmg as pure dpsers like locks and hunters. Main reasons for having spriests would be raidutility cause of that.

To clarify, yes, Shadow Priests generally don't top the DPS charts, but they ARE a buffing class, so that's to be expected.  Assuming equal skill, they'll always come below Hunters, Warlocks, Mages, DPS Warriors, and tend to be above Shamans (Elemental or Enhancement), Druids (Balance or Feral), Pallies (Retribution).

That said, of course, because there's so much room for skill in a Shadow Priest (getting down rotations, watching timers, etc.) compared to, say, a BM Hunter (gogo BM Hunter Macro), a good Shadow Priest can consistently be amongst your best DPSers, and a bad one can be along the bottom.  For instance, we have two Shadow Priests in our raid that are similarly geared, but one is consistently in our top 4-5 DPSers (and probably the lesser geared of the two), and the other tends to run around 10th.

ETA:  Also, DPS output from Shadow Priests just doesn't scale well.  That is, they'll tend to be one of the best DPSers in places like Karazhan, Gruul, and Mags.  They'll start to slip in SSC and TK, and even the best ones can't hold the top spots when everyone starts getting Tier6 gear.

^^ completly agree.

For some strange reason i dont bumb into good skilled or even descent skilled spriests on my server only slightly retarted ppl seem to choose a shadowpriest as class.

One that specced full shadow, except vamperic touch for example.. and another one didnt use it and only used shadow word pain and mindblast. When i asked what he did when mindblast is on a cd the answer was, i spam shadoword pain....

You put Enh Shammies in the '2nd' catagory? You been playing with some lousy Shammies.....

Quite the contrary.  Enhancement Shammies are excellent, and they're great for the raid, but they're ultimately a buffing class and will always be out-damaged by a pure DPS class.  If you have Enchancement Shammies doing more DPS than a Rogue or Fury Warrior that he is buffing, then it's the Rogue or Warrior who is the crappy player.

Also, that's not to say they do crappy damage, 800 DPS is nice, but when the Rogues and Fury Warriors are doing 1200+ DPS, they just can't keep up.  Of course, they're still invaluable, because they easily account for 20% of a Fury Warriors damage and a nice percentage of Rogues too all thanks to Windfury.  So, I guess if you count the damage the buff others for, then I guess they technically bring more DPS to the raid, but only if there's the pure buffable DPSers there to get the buffs.

Either way, you effectively have pure DPSers and buff DPSers.  If one of the second type is above one of the first type, either there's a big gear discrepancy, a big buff discrepancy, or a big skill discrepancy.

I underdstand what your saying, but gioving them credit for the DPS they are getting because I through down grace of wind, strength of earth and flametounge isn't fair. Thats NOT thier damage, that's mine. When you say Shammys are in the '2nd' catagory for damage, its ONLY because we gave the rogue, hunter and warrior buffs. You put equally geared ENH shammy against a Fury warrior WITHOUT our buffs, we will out DPS them anyday. Same goes for rogues unless its an amazing player.

I agree on the Fury warrior point, Windfury is like Night and Day for them.  However, I will disagree that a rogue without an Enhancement Shaman won't still out DPS an Enhancement Shaman.  Either way, the point is still that pure DPS classes are designed so that they don't offer much in the way of buffs, but are highly buffable.  And comparing the DPS from various classes just doesn't make sense unless you're assuming raid buffs or fully unbuffed.

To make it relevant to the Priest forum again, it's like comparing a Paladin's longevity with Pally Blessings, to a Priest without them.  I gain at least another 250 MP5 OO5SR and 140ish I5SR when I'm fully raid buffed, and a lot of that has to do with Kings and Wisdom.

Either way, the point is, some classes you bring because of their DPS, and some because of their buffs.  A rogue or fury warrior is in the first type, enhancement shamans are the second type because, all things being equal, the first type will do more dps but not without the second type buffing them.

shadow priest are very usefull, to have at least 2-4 in a raid----but i have heard that the shadow priest got nerfed 2.4 patch i dont know if its true that why i seen alot of shadow priest switching to disc/holy ??

No, Shadow Priests were not nerfed in 2.4.

And 2-4 in a raid?  I've seen some of the very high end guilds do that on first kills, but in general, 3 Shadow Priests is REALLY pushing it, where 2 is probably the optimal number.

They didn't get a nerf that patch. But they did get nerfs with every patch since BC was released.

It's because they're Soul Linked to Warlocks. Both classes function more-or-less the same way so a nerf to one affects the other (see: Fear nerf)

For PvE, you are basically a mana-battery for others...

Just continuing the quoting =]

You mean like when Meditation when from 15% to 30%?  No wait, that's a buff.  How about when they changed the spirit mechanics in 2.4?  No wait, that was a buff too.

Which nerfs are you talking about?

i enjoy sp more than any class. sure you will feel like your not hanging on damage meters like top classes, but combine the damage and healing and you end up doing alot of help to raid/grp. also, sp does not have the pure burst damage, more sustained. example; usually in a 5 man, i will be around 15-20% of total damage on meter, but then on boss fight (that lasts for a longer time) i can see the percentage increase by 5-7% in a couple minutes. wicked. plus, any class that can return mana to a grp during combat is uber usefull.
