First off: as of right now, there still is no Resto druid relic on the PTR. Didn't mean to get your hopes up.... I know, I'm a very mean tree. Sorry =( See, I've been on the look out for any kind of new druid relics that might be out there, dropping from bosses in Ulduar, but so far, no luck. Correct me if I'm wrong, but it looks like there is a total of four that have been reported: Libram of the Sacred Shield, Idol of the Corrupter, Idol of the Crying Wind, and Steamcaller's Totem. But none yet for us trees.
Depending on how you choose to heal after The Great Lifebloom Nerf of 2009, the current relic we've been using, Idol of Lush Moss, might not be all that viable anymore.
So what should we use after 3.1? Last I heard, the Idol of the Raven Goddess doesn't work with our ToL aura anymore, so that's out the window. The Idol of Awakening, which drops from Gothik in Naxx25 might work well, especially with the Great Mana Regen Nerf of 2009 - we may need all the mana we can get our little barky hands on. There's also the Idol of Pure Thoughts to consider, which you can buy from the Grizzly Hills vendors using Venture Coins.
Although, hey, if we're going to let Lifebloom run out and bloom everywhere and on everything (kinda sounds kinky, don't it), perhaps we should start looking at the Deadly Gladiator's Idol of Tenacity, which is (obviously) the PvP relic for healing pvp druids.
Or perhaps most people will just keep their Idol of Lush Moss... regardless of whether you let LB bloom or not, it's always going to tick first.
What do you guys think?
