Yeah the dragons do have some nifty non set items like I said. If you look at the AQ sets your right they do (for most classes) seem pretty geared towards a different play style, i.e conquerors seems more dps like etc. Then again AQ set was only 2.5 and is like an aside. They seem to have returned to normal with this tier 3 set.
Don't get me wrong, I'm not saying "zomg get out of cat form and heal" because I know and fully appreciate the benefits of having so many druids doing different things within the raid group. What I am saying is if you want to go to that different play style then, yes there adequate gear out there for that. Just don't tell me you expected tier 3 to be an all out leather tanking set, 'cos it wasn't happen. If they did make the set's more hybrid you would just complain as you wouldnt have as specialsed stats in any of your sets and would end up being able to do a little bit of everything but none of it as well as it could be done.
