Counterpoint, I don’t ever bother fearing a priest. I just curse of tongues, drain their mana and kill them at my leisure. WotF doesn’t change Lock vs Priest. Priest still loses.
Fear Ward vs WotF. Fairly close. Both have advantages. Fear ward can be up and have another ready, but is dispellable. Wotf can’t be, but it also can’t be used on others. Desperate prayer and stone form are also quite nice. Rather have those than Cannibalize or DP.
WoTF doesn’t change Dwarf v Undead matchup too much. It does mess with other priest matchups somewhat. IMO, WotF is for Rogues. They are the only ones it actually helps with matchups on.
Undead mages vs Shadow priest or Warlock? They still lose. WoTF doesn’t help.
