Well, the speculation that the Holy Pally T14 4pc bonus would be nerfed has made its way to reality in the 5.3 PTR patch notes.
Tier-14 Holy Paladin 4-piece set bonus now reduces the cooldown of Holy Shock by 1 second, down from 2 seconds.
Not really surprising, considering how overpowered Holy Pallies considered their previous tier’s 4pc bonus, but also gives pallies some time to get their tokens before patch 5.3 drops and the nerf comes into effect.
Fortunately, there is also a change in the patch notes that buffs Daybreak, something that Pallies thought was quite underwhelming. Here are the T15 bonuses:
2 pieces: Increases the healing done by your Daybreak ability by 50%.
4 pieces: Increases the healing transferred to your Beacon of Light target by 20%.
And here is the buff to Daybreak:
Daybreak is now a stackable effect with a duration of 10 seconds, stacks up to 2 times, and causes the next Holy Shock to also heal other allies within 10 yards of the target for an amount equal to 75%/150% of the original healing done.
The buff might not compete with the pre-T14 bonus, but does make the T15 a bit more appealing to Pallies upgrading to T15.
