In Season of Discovery, the Tier 2 6-piece bonus for Holy Paladins causes your melee swing timer to reset every time the associated beacon healing procs (i.e. on every cast of Holy Shock, Exorcism, Holy Wrath, and every tick of Consecration) Effectively you can almost never complete a melee swing. This not only dents ouput massively, but also prevents fishing for Art of War procs to drive additional healing/dps.
It’s a huge bummer. I was excited to play the spec, but I’m afraid myself and others in the raiding community have deemed the healing shockadin spec DoA due to this rather substantial issue.
