I do not do this often.. because I like shadow priests much.. myself I am playing one as main atm. But I must agree with above posters. We are not in par with the other classes damage wise at the moment (patch 2.4) I am not saying we do not deal damage.. hell I can slay any undergeared player, but who doesn't.
With all the changes to resilience affecting crit, dots, manaburn, and forgotten scalability after TBC. Spriests kind of lost burst damage and a big piece of utility. So much needed in 2v2 setups. Yes you can max out shadow power, but if you think that critically hitting yourself in the combo MB + SW: D is way to go suit yourself :)
Pro's:
I am still owning any warrior, this goes up to them in vengeful gear, as priests always did. Feral Druids, not sure if it is only me but I have only encountered very few good ferals so far. And they are usually surprised as their HP goes down and they try to heal too late and "whoops there goes a silence" and they are gone after that. Resto druids.. well this can be issue. although they are usually unable to kill me, I am not able to kill them. *sigh* Boomkins.. they usually have low HP (under 10K) for some reason and are not a big issue (however they improved with 2.4) + Any undergeared nubcakes. And that's about it.
Con's:
Mages, if they outgear you slightly they have SICK burst damage, hard to handle. But still fair fight usually. Rogues as expected.. way too much CC to handle easy for a spriest in most cases. Hunters.. well it depends.. but if you have nowhere to hide you are in trouble. Their burst dmg is SICK and I have seen many cases when hunter did more dmg then me + 3/5 vengeful mage together in 2v2, note I have 456res 735dmg and mage 410res and about 835dmg that basically says it all. Same goes for enh. shamans if they get to you you have an issue. I remember clearly I was 4 shotted and I have 10.8K HP self buffed. Agreed that the shaman had stormherald but.. I just want to say that when geared properly their burst damage is SICK.
What became of spriests? I think they are kind of sloppy warlocks atm. They do only damage over time, lacking burst damage when compared to other classes in same gear.
I am respeccing to disc/shadow dmg build today and will see. If it does not help I am going to my warrior in S4 and will regear him. The spriest will go to hibernation mode until Blizz will come up with something.
If you want to make PvP char, spriest not recomended atm. (this might change however) because Blizz has tendency to fix the class you just stoped playing..
