"Last month, Blizzard dished out the deets on how World of Warcraft: Classic’s content will be divvied out in six discrete phases, but the plan was notably lacking PvP-related information. But if you were worried that WoW: Classic wouldn’t hearken back to the olden days of endless ganking in Southshore and Stranglethorn, worry no more — the devs have laid out their plans for rolling out PvP content.
Like the PvE content, PvP content will trickle into the game in six phases. In phase one, PvP will be exactly like it was when World of Warcraft first launched — i.e., lawless and full of ganking with neither reward nor consequence. Phase two will introduce the honor system and PvP rank rewards, and phase three will open the gates on the game’s first battlegrounds, Alterac Valley (which is coming in its patch 1.12 flavor) and Warsong Gulch."
