I've heard a lot about the Necro/Shm business, but how effective is it in a dungeon. I'm assuming I'm relying 100% on root inside a dungeon. The DoT's I'm sure will be more than efficient, but would I still be using nec/shm pets?
As far as end game, Druid's aren't as versatile for a group that a cleric is just that important for a little grind group? I mean I understand that the bst and it's pet would never need to worry about regen, however dps would really really lack. Wouldn't it?
If you are just worried about grind groups, it really doesn't matter between BST/CLR and BST/DRU. Both will do just fine and you will be able to do Tier 2 or Tier 3 PoP content with just those two classes. You have tank, heals and slows covered so you can pick any other 4 classes to join you for great exp. The monk/shaman provided the same basics when I initially leveled up so it was nice to start your own group at leisure.
Remember, we are capped at 65 on this server with PoP AA's. If you play long enough, you will get to the point where you effectively max out your character exp and AA-wise. At that point, you will be looking for high-end content challenges. With that, the CLR will give you more options than the DRU but it is really your call.
