I was thinking, if you use Soul of the Forest and then lifebloom, it has bonus ticks. If you just keep refreshing it with other spells, will it keep those extra ticks? I have a bad habit of refreshing with Lifebloom again, but if it keeps a 75% haste buff that would be a huge increase in heals with minimal changes, and I'd only need to use one swiftmend for it.
No, as soon as you refresh your enhanced LB, whether from a direct cast from LB or from a direct heal, it resets the HoT to your current haste rating. However, with that being said if you use your SotF proc on a direct heal to refresh LB it will gain the 75% haste bonus also.
