Many healing classes got fun and interesting changes and additions to their play styles. Pallies had a complete overhaul from what I've seen (although I don't have one). It seems to me, the opposite has happened to druids. We didn't receive any new spells to add to your so-called "bag of tricks". Disc and Holy priests both have new spells. Pallies have many new spells. I really don't know whether or not shammies have new spells. Either way, I feel like I'm lacking that new flair that should come with an expansion.
Not only did we not receive additions, we lost some of our core druid flair. Resto druids are supposed to be masters of HoTs...I mean it's in our freakin' spec description! We never really relied on direct heals. Rather, we used multiple HoTs to heal incoming damage. I feel as if we've moved pretty far away from HoTs. Regrowth as a HoT, for all intents and purposes, has been removed. Even when the time does call for our quick burst heal, the actual HoT portion is pretty negligible. In fact, I find myself using direct healing spells more frequently than my HoTs. I understand that we can no longer Rejuv the entire party/raid, but that doesn't change the fact that the core challenge for a druid is to know when to apply HoTs. There is a little bit of that left. We can still cast Rejuv if we know there is incoming damage, but that sense of being the healing version of an Affliction lock is gone.
I will admit that as an 84 druid I still lack a lot of experience with the new system. However, I feel as if druids are moving away from our core healing over time design towards direct healing and that I should maybe just look into another class that does direct healing better.
Recommendations: I think introducing a new HoT spell will not only elevate druids back to HoT masters but will also add some desperately needed reinvigoration, as other classes have gotten. Perhaps a HoT that acts similarly to Nourish, low throughput/high efficiency.
Regardless, I'd like to hear what other Resto druids have to say and to see if anyone agrees.
Note: I haven't been involved at all with Beta. So, I don't know what druids had at their disposal during that time.
