This was the case when you could spam macro “/stopattack /startattack” on classic release and do a machinegun when fury warrior/rogue is attacking you. Then they nerfed the melee swing reset thing and we had to constantly run around in pvp toggling off our attacks. It still worked, because we could easily stack on mobs because of batching. In SoM they killed batching.
Overall it is still the only viable spec if you want to hit some faces with 2h in pvp : solo, bgs.
Redemption holy teddy bear is only for grouped pvp, since you can’t even kill anybody, because it has 0 spell power.
