Here are some of the upcoming resto changes, as reported by MMO.  

Restoration – Gift of the Earthmother now increases your total spell haste by 2/4/6/8/10%

Glyphs -Glyph of Rapid Rejuvenation – Your haste now reduces the time between the periodic healing ticks of your Rejuvenation spell.

Item – Druid T10 Restoration Relic (Rejuvenation) – The periodic healing from your Rejuvenation spell grants 32 spell power for 15 sec. Stacks up to 8 times.

Rebirth- The cooldown on this spell has been lowered from 20 minutes down to 10 minutes. Cannot be used in Arenas

So at first glance it looks to me like, while stacking crit seems like a good plan in tier 9, stacking haste will be the way to go in tier 10, if we want to keep our nice short global cooldown we have form the current “Gift of the Earthmother”.

The new glyph is interesting. If rejuv still runs for the same duration, and just clicks more, then it’s a definite must have. If it shortens the duration, I might have to give it some more thought.  But if it’s jumping around with the t10 set bonus, maybe a slight reduction in duration wouldn’t be a huge deal.  

The idol is basically 256 free spell power, up from the 234 from the t9 idol.  

And reduced rebirth CD, well that will come in handy I’m sure
