While Chain Healing is a resto shamans niche healing spells, it is always been unfortunate that it drops in effectiveness with every jump it makes between raid members. However, in 5.4 shamans will no longer see it decrease per jump. Instead it the healing will remain static for every jump it makes.
This will also make it that much more important that resto shamans are chain healing off someone who has Riptide and/or Earth Shield since the jump healing will be so much more noticeable.
Of course, Blizzard could still change it at any time until the patch releases, but this is one of the great new buffs given to resto shamans for 5.4 .
