Holy frustration!

Just ran a team of druids to 28, wow am I frustrated!

My tank dies non-stop. It's quite insane how easy he dies.
I can't even do Scarlet Halls I die to the first boss over and over.
The ads kill me before I can kill them.

No threat issues, I just can't spam nourish enough with hots.

I ran a team of 5 to 30 the previous day, Warrior 3x Mages 1x Disc. Priest.
No issues, the warrior is very solid no close calls really at all. I breezed through
each dungeon without problem.

My druids are spamming moonfire, I assume this is lackluster but not causing the deaths.

Can someone please advise, perhaps some better DPS macro's/AOE ones as well? On another
note the character are dungeon geared, missing plenty of pieces however, my other team
was just as poorly geared.

Any advice?
