Tier 10 Shaman Setboni
The new Tier10 armor sets are in the making and so are our newest set boni. As stated several times by Blizzard Staff the numbers are not final yet.
2 Pieces (Resto): Your Riptide spell grants 20% spell haste for your next spellcast.
4 Pieces (Resto): Your Chain Heal critical strikes cause the target to heal for 25% of the healed amount.
The first bonus seems nice to further reduce the time till the next cast lands after you just cast Riptide and waiting for your global cooldown to finish. Some might argue that this is a fine thing to throw out a very fast Chain Heal practically doubling your haste bonus for this one spell. However recent calculations found on the mmo-champion shaman forums indicate that using Riptide every cooldown to boost a ‘Chain Heal Spam’ is actually a -decrease- in healing per second!
The 4 pieces bonus is yet to be tested. If the extra heal is capable of proccing other spells and abilities (e.g. Earthliving Weapon) it could be quite useful. Time will tell.
