There’s a ton of awesome PvP-related stuff happening in Warlords.
CC Disarmament: there’s a lot fewer CC spells, especially instant and auto cast CCs, and more shared DRs among the ones that remain.
Health and scaling rebalance: means little to no Base Resilience or Battle Fatigue are needed, and classes that aren’t as reliant on gear to perform. Also does wonders for PvP class balance.
Ashran: Blizzard new open world PvP zone, which Blizzard are not quite ready to share details on yet.
Skirmishes: unrated Arenas that can be queued for either solo or in a group.
Spectator invites & Tournament gear: additional tools to allow tournament organizers to run high-quality tournaments without needing direct intervention from Blizzard.
Blizzard new built-in Group Finder: much easier way to find party members for rated BGs or Arenas.
