For a Druid tank, I would say the design is very, very poor. The majority of our utility require us to shift out of our tanking form in order to use them and, if Blizzard wants tanks to actively tank something more often, then all of that utility becomes useless. We have a couple of ways around this through our lvl 90 talents, HotW and DoC, so that we have the ability to throw some minor off-heals/battle rez in form, if necessary, but that doesn't solve the problem of all of the other things we have.
