Belo'ren Raid Guide
Liquid has defeated Heroic Belo'ren already, but some hotfixes have been pushed to live servers which retune some of the raid damage on the encounter. Burning Heart is periodic ticking damage through the encounter and Voidlight Convergence is burstier damage when players are given a color.
Normal Burning Heart base damage increased by 50%, but scaling coefficient removed.
This will increase the damage taken on small groups by up to 50%, and have no change for a 30 man raid group.
Heroic Burning Heart base damage increased by 33%, but scaling coefficient removed.
This will increase the damage taken on small groups, and decrease the damage taken by large groups.
Normal Voidlight Convergence damage increased by 25%
Heroic Voidlight Convergence damage increased by 66%
It's unlikely that this will do much to the overall healing requirement, but Blizzard may have thought that small group sizes for Belo'ren were too easy and wanted to beef it up a little more.
