PHASED CONTENT ROLLOUT – Following its launch, World of Warcraft Classic’s content will be released over the course of multiple phases reflecting the game’s original order. Re-experience WoW history unfolding as heroes gear up for Blackwing Lair; players battle for PvP Honor and Rank rewards; and entire realms band together to open the gates of Ahn’Qiraj.
The primary goal of Conflict and Strife is to provide an interesting choice in PvP by allowing access to an extra PvP Talent. It’s not necessarily going to be a strong option for PvE. The acquisition of this Essence is via PvP, and is totally optional for PvE-focused players. While there may be interesting PvE uses for some of the choices, it is not expected to be a strong competitor on usual PvE criteria (like total throughput) on every spec.
