I honestly find being a resto druid a challenge in arena.... even being somewhat of an offensive go-to person in BG's.. tanking multi-mobs, switching to bear and stunning people, going back to tree and healing/wf/rejuv'ing your group so on and so forth. I guess my point is the flexibility of a resto druid is good in many ways but DAUNTING in others... (especially with hybrid specs..) pocket healing though is easy shmeasy
