Ok. So Starsurge instant cast would be interesting, along with the Entangling Roots change.

I can see a situation where one casts instants almost exclusively and continually weaves in...

Moonfire,
Entangling Roots,
Starsurge,
Typhoon,
Solar Beam,

That would allow a boomkin team to just stay completely mobile and still wear people down. Looking at the Starsurge change, it looks very much proc-based, which is doable but not as nice if that big damage ability was actually always instant cast.

On the whole, I am still very concerned. I just don't see huge bursty DPS numbers out of boomkin on the PTR like I do from the shaman. I also think the eclipse mechanic, while not impossible to manage, is a big part of druid DPS and will take some managing. The fact that it's crucial to mana recovery is also concerning.

I'm just cautious. Shaman changes look like they're all good, where as the druid changes are really going to require an analysis of how things might play out at L85 to understand.
