When I first played this character it suited me well and I kinda loved the playstyle.
For me there is no better pvp, than a slow-phased with a complicated variety of skills and tactics. So I decided to play one seriously.
I would like to know witch among all buffers will help me most. Im not talking about support, but buffs.
Is it the prophet with his prophecy and critical boosts. Or is it the elven elder with the advanced block/blessed shield/resist shock/clarity. Maybe someone else.
I tried to compare them, but Im bad at making choices. So its up to you to shake the balance.

I searched all over the forums, so dont tell me i didnt

well, PP is the most complete buffer, and as u are SK, u will rely on RB/cata mostly (at least at high lvls), this means that u will need all the defense u can get. Well, u have 2 options. PP with more and more variety of buffs, with bless shield. Or EE, with not so many buffs, but good to have when u tank, he has bless shield, advanced block and resist shock, as u said. Clarity might help with aggro too. But I think that, generaly, PP will fit u. Its the most versatile buffer, he lacks empower and VR, yes, but u dont rly need VR if u dual box ur PP, u can for example have him sit and from time to time heal urself with it. Sk is a good solo'er with cubics, hex and the appropriated equipment. So, I'd go for PP, but u can also choose EE when u go raid/cata, or maybe u will have one in clan/party/friend (also good in cata for the unholy resist)

SE.
Sk is a half mage/half fighter. W/o magics=it sucks.

for pve the best buffer for a fighter is always a wc

Still, an SK rly needs empower+acumen. At 70+ hex needs empower for exapmle and you'll lose too much hp so you'll need to use the 2vampiric spells often also the power break.
Sometimes a lightning strike can be useful too, not to mention the pvps.
Yeah, no bless shields, grmight and such stuff, but there will be empo/wm/guidance/focus/dw/shield/might, also heals and recharge and you can use greater haste/swift/magic potions.

Some SK goes with mage sword also.

I would say Shilien Elder(empower, vampiric rage)
WC is verry good too. But only for 4+ parties

Agree. Emp and acumen potion. Hex is gonna land almost everytime, and you'll leech some nice hp out of the enemy.

I believe the only dangerous enemy at pvp are nukers. It is good to have those 2 drains and debuffs at a moderate stage with SE, but nukers are made for nukes. They will do more dmg than i do and we have the same range.I dont think I can beat them with their own stones. Hex, phantom and power break will be useless regardless their land rate. I think should play my SK, the way I can stand a chance against every class. Am I saying the truth or im fooling myself?
I also compared prophet/ee with a little help from the ch buffs:
PP:
physical dps=493.5
p.def=1676
m.def=1471
(100% block without toggles)

EE:
physical dps=289.9
p.def=1758
m.def=1742 (100% block without toggles)

EE is just the worst buffer.
Go for SE, that's all I can say and against nukers, well, get mdefbuff from somewhere and you may have a chance.
You still have quite a good resistance, so you can keep up maybe with cppots.

Well then, I should pick a SE. I respect all of your opinions. I actually didnt expect ending up with that choice. I was planning to use DC heavy for 100% block, so i wont need it anymore. Will majestic heavy help me out form stuns or I should find a clan hall and get magic barrier/bless shield. I also got an idea for fighting nukers. Is rooting them and using ud while draining the shit out of them possible?

Root+hex and go for them.
Majestic hvy might be better than dc, you're screwed up if someone stuns you.

Is this with Berserker Spirit? Never put it on a tank..
I suggest WC - crit power, rate, haste, might, shield, greater might/shield, CoV, vampiric, reflect..
I mean.. what can SE offer you? No haste.. no greater might/shield.. no CoV.. no reflect.. ok you got Empower but what for? It's true you got magic skills but you are a fighter anyway.. will you give Haste, greater might/shield, CoV and reflect just for Empower?
The only problem is WC's buffs require high MP, but afterall they last 20min so he can buff you and even your party if you have one..
About EE - you really need stun ressist but if you can get Majestic armor and eventually some boss jewel its not needed that much..
And also majestic heavy really fits a dark elf - 50% stun ressist, +2 STR (you got a good P.atk bonus cuz u already have high STR) -2 CON (its ok, you dont lose so much since u have low CON) and some accuracy..oh and the 4% p.atk which you will need as a tank (with low atk) and its awesome vs mages..
Thats what I think.. and thats what I would chose..

That's what I'm talkin about. SK is somewhat a mage in hvy armor, for pvp I would go for SoM+acumen instead of dle, to land the debuffs fast and drain as much as I can.
For CoV, yes it is needed a lot, coz Powind is only good for bosses imo, but 'til that for lvling, recharge/heal and empower is what a SK needs after all.

i think its better a som magic power cuz u hav already low casting and 15% cast speed isnt that much....for pvp oly style without cp/hp potion is ok to use mag weapons but in free pvp damage made by your drains can be replace with only 2 cp pots

Yeah, maybe a fighter weapon should be in hand too.
