So my plan for this week's column was to talk about how balance currently looks in the beta (short version: pretty good), but judging by a quick scan through the beta forums, that's not what druids want to talk about. It's Symbiosis, all the way down ... and judging by the discussion, most people don't like what they're seeing. Allison's already written about it once before, but the topic's grown enough to where it deserves another treatment. (My blog contains a full breakdown of what each class currently gets and receives from the ability, along with more in-depth recommendations and strategy.)
I'll be blunt: I still love the unique concept of Symbiosis, and I think most of the criticism is shortsighted. I do have quibbles about some of the specific abilities. Overall, though, I think that the concept works and will provide access to some entertaining abilities we haven't had previously.
To be fair, however, let's look at some of the more common arguments against Symbiosis and attempt to deconstruct them. One important thing to note: Many of the abilities gained/given from Symbiosis are modified from their original forms, so read tooltips carefully (and realize that many are not updated). The Symbiosis version of Mirror Image, for example, is much weaker than the version used by mages.
