A recent bug was reported where
Vision of Unending Growth was only giving around 2% proc chance instead of the 2.5% proc chance and should be corrected soon. In addition, we received confirmation that the proc chance for partial ticks is prorated to smooth out the increased healing provided by reaching the 20% haste breakpoint.
What this means is instead of receiving a full
Rejuvenation proc chance regardless of the size of the partial tick, the partial tick's chance to proc an additional
Rejuvenation will be proportional to the size of the partial tick. For example, if the partial tick is only 50% of the healing of a full tick of
Rejuvenation then it will have a 1.25% chance to proc an additional
Rejuvenation instead of a full 2.5% chance. This essentially removes the significant healing increased by hitting
Rejuvenation haste breakpoints. Haste will still be valuable for this legendary but there won't be sizable healing step increases based on
Rejuvenation haste breakpoints.
