Both get parties REALLY easy, Go with the class that you think seems most fun since they are pretty much the same. But sws is a little better for pvp and bd better for pve..
I think a BD has more chance of finding groups then a SWS ... But... there are probably fewer SWS then BD's out there ...
On one hand the BD has dances for nukers and fighters, all geared towards dmg and on the other hand u have the sws with only 1 true dmg song, hunter, only usefull for fighters, the rest being defensive buffs.
But i love em both just as much :) And i agree with what every1 else said
Oh and on a side note, if u go sws, think twice before makin him a male, and a female BD >< Their song/ dance animations are horrible compared to what u get with a female SWS and male BD, it's really 2 bad cause a dark elf female looks reall nice :) But it's up to you really
Either one will be a good pick. both find parties faily well ( bd prob easier ) and both are great additions to pvp and pve parties. But remember as of now the damage buffs out do defensive ones. sws is defensive and bd is offensive so in 1v1 bd is better off than sws. at top lvls, bd's get dances that will fit most if not all pvp and pve occasions. i just think bd is more flexible.
ok the main thing is really, Sws=more defensive(song wise its almost all +defensive stats such as mdef,pdef,and reists, cept for hunter which is awsome). Bd is more on the offensive side and alot more active skills.
Sws has is arrest, physco symphony, entangle. Bd has Hex, sting, frezzing strike, arrest, Powerbreak, posion blade dance, Demonic blade dance.BD has a much higher dmg output(most of the time) then an sws due to higher str and dual mastery, also the BD dances +++ offensives such as atk speed, patk, crit dmg, but BD do lack on the Con side from the start then -more con with armor stats and other tats.
However, Sws dont go down easy and i have beat nukers my lvl in 1v1 a buncha times due to the High mdef (song of warding) and the resist songs to nerf the dmg from Fire, wind, and dark magic.
I'll talk about PVP. They both hold their own, BD in damage and SWS in defense. When it comes to PVP I'd rather have the BD only dance 2 while the SWS will have to do at least 3-5 songs depending on situation.
An SWS is the Necro's worst enemy, indirectly ^^ Combine that with an Eva's saint and expect dark vortex to do 3-400dmg on you BUHAHAHAA!
Dance of Fire also appears to be getting the nerf stick in the Thronicle (by how much, we do not yet know). That's pretty much the most powerful BD dance there was. What will happen now remains to be seen. (Of course, Fury and Warrior are still useful - they just couldn't ever compete with Fire before. :p )
sws' really start to shine once they get prophecy of wind too omg its like dance of fury 2x but then again I am a bd and I love being almost 74 and never needing clan hall VR again and just use my prophet down in the cata.
I played a SWS on the c4 PTS and hated it. It was no problem finding groups but I felt like I didn't do much damage and they have essentially no skills except for their songs and hamstring. In addition, on retail, most xp parties will go out with a bd but no sws, but few will head out with a sws and no bd.
I therefore made my sub a BD. Lots of fun pvp/pve skills, easy to get parties with. Decent at soloing, good at duoing, great in groups. Hard to beat that.
