I have only 7268 Honorable Kills on my warlock. I scored a few during a cross-realm Sha of Anger raid hosted by a PvP realm, but I've only played casually in random battlegrounds in past tiers. My experience includes memories of an SL/SL demonoloy lock in Isle of Conquest during Wrath of the Lich King and dealing with the, shall we say, "vicious" turnover of the Season 9/10 gear transition.
Everything's a bit fuzzy for PvP in between those memories. Recently, I'm sure my DoT dominance of battlegrounds was due more to my company of guildmates, my Dragonwrath, and my heroic Cunning of the Cruel than any skill I had, but I'm not entirely new to flinging my enemies around in fear.
But this is the warlock column, not the Warlocks-Who-Only-Raid column. While I reach out to warlocks around the world for warlock-centric PvP advice, how about we peruse the gearing options for dipping our toes into level 90 PvP?
