Divine Plea has already seen a change in that it no longer reduces healing done by 50%. Now they have also changed the mana return. Divine Plea will now restore 12% of total mana, plus an additional mana return based on the Pally’s spirit.
It will be interesting to see if this ends up having any impact on the amount of spirit Holy Pallies stack, especially because many reduced spirit because of the meta. The exact amount of mana return from spirit hasn’t been announced however.
There is also a new major glyph, Glyph of Divine Plea, which will cause it to restore 15% of total mana instead of only 12%. This changes the current glyph which caused it to have a 5 second cast time for 12% mana with no healing reduction.
