Not that I ever remember in vanilla, no. It was rather important for me, since I had to do all my shard farming the night before a raid, since I got out of work with ~45-1hr before my raid, and my commute took anywhere from 11minutes to 1.5 hours to travel the roughly 3 miles… I’d literally log on and get summoned to the raid to help summon people myself many days.
SM/Ruin… Hybrid Dot/Nuke build… Pretty damn great at both individually. Potentially the single strongest build in the history of the game. Susceptible to shadow lockouts and tendency to be glass cannon. Also one of the two top PvE builds, so it’s extremely common for raiders that also pvp.
NF/Conflag… same as above, loses a bit of bite on Sbolt/Sburn, dot power, and utility for Conflag. Basically a slightly more consistent, mobile, nuke oriented version of SM/Ruin. Also mixes fire and Shadow, so getting locked out hurts it less… Probably my favorite build overall for pvp… I typically swap to this once content is on farm and I can afford to lose 10% on sbolt in PvE. Also glass cannon
Deep Destro:
You give up basically all but basic dot power to maximize direct damage potential, and boost personal survivability… Tankier than NF/Conflag and loses range on curses + nightfall procs (instant shadow bolt procs off corruption dot ticks)… Typically utilizes maxxed Searing pain talent, and usually prioritizes fire based attacks.
SM/DS: Depends on what pet you sacrifice (VW for health regen, Succubus for an additional 15% shadow damage on top of your 10% from shadow mastery)… VW sac gives you basically unlimited mana (via constantly regenerating health, which you lifetap for mana)… I’d sac a VW in AV zerg fights to never stop tab-dotting things, for example… Succy sac with this build provides some absolutely absurd scaling at end game and you will be able to 100-0 people with just corruption/agony/siphon life if they aren’t healed or dispelled, assuming decent gear… Both variants just tab dot things and either searing pain or drain life spam as a filler.
Soul Link/Nightfall: Take the playstyle of SM/DS… give it a pet, near immunity to casters, and 4x the health at the cost of most of it’s damage output. It’s the best “dueling build” and you basically just stand around dotting things and being incredibly obnoxious to kill.
Soul Link/ Shadow burn: The standard Soul link pvp build. Plays kind of like a short ranged version of SM/Ruin with no gimmicks. You don’t get the big ruin bolts, you don’t get the instant nightfall procs, you don’t get either range talent, you don’t siphon life, and you don’t get curse of exhaustion… What you do get is a near immunity to casters, a fairly stupid amount of effective health and a whole lot of consistency. SM/Ruin is higher risk/reward where you can swing for home runs… Soul Link /Shadow burn is like a guaranteed double.
