I have been playing druid since season 4 and have stuck to it ever since. Even through the dark days of season 11, when resto druids were a considerably weak healer, I enjoyed playing my class and spec. I even found myself playing underdog compositions in 3v3 - WLD in S9, RPD in S11, RLD in S11/S12.
Lately, however, I have begun to lose interest in resto druid and I slowly find myself playing less and less arena. I fear that resto druids will soon have the same status as they did in S11 and will ultimately wind up as a less desirable healer.
One of the primary reasons I have this superstition is because of the 5.1 change to Battle Fatigue combined with the popularity of Warriors in 3v3 arena.
It has become quite clear that there has been a shift from constant damage in arena to burst damage. Comps like Affliction Lock, Resto Shaman, Boomkin and Affliction Lock, Shadow Priest, Healer are very rare on current arena ladders. Burst damage comps such as Arms Warrior, BM Hunter, Healer and Arms Warrior, Feral Druid, Healer are currently very popular.
Countering burst damage as a resto druid has always been pretty difficult. I'm quite certain I am not alone in the opinion that Resto Druids lack a powerful burst heal. With the rise in popularity of high burst comps in 3v3 and with the nerf to PvP healing, I find resto druids as one of the least suitable healers for competitive 3v3 arena (especially if you're like me and run underdog comps).
I know some people will be inclined to mention that there are resto druids who are successful this season, namely Starship, Shouri, Sodah, Mayo. But I think the success of the few is no remedy to the hardships of the many.
Likewise, arena representation data above 2200 is complicated as many teams on Battlegroups other than Bloodlust are inactive.
I have done some testing on the PTR and have dipped my toes into 3v3 Arena. Overall I am a bit disappointed with some of the class changes for resto druids (and at the same time very optimistic about Rogues). Displacer Beast, while being one of our most powerful survival tools, is otherwise rendered useless without an instant prowl. Resto druids have historically been very susceptible to hard swaps (with most of our survivability coming from the ability to preemtively swap hots). Displacer Beast was a potent boost to our survivability. I would have rather seen an increase on the cooldown instead of a change of its effect.
Cyclone DR is also a change I hope does not make it to live. Though I am incredibly biased as I play with a rogue, the change is detrimental to Rogue/Druid and Mage/Druid synergy. Druid/Rogue openers (sap on one target, clone on other; clone onto sap target) are significantly weaker which wouldn't be a problem if it wasn't for Druid/Rogue openers being crucial to the flow of a 3v3 match. I imagine playing with a mage will require impeccable coordination and timing.
As for some final notes, here are some things I would like to see changed with the druid class:
Symbiosis granting abilities like Ice Block, Dispersion, Divine Shield is ridiculous. Symbiosis should not grant major cooldown abilities.
Tranquility COULD use a touch up. As far as I know, it barely heals for more than Healing Tide Totem. Maybe increase its cooldown, but make it an instant spell with a targeting circle that lasts for a specific duration.
Clone Range should be a baseline 29 yards.
Heart of the Wild wrath damage as resto is considerably high - I have had 3v3 games where I have out damaged my rogue partner.
Any feedback is appreciated! A big thank you for anyone who took the time to read this!
