That's the same level my shamen entered ZF at the start of the weekend,
somehow the first gauntlet event went without any trouble.
The second time I ended up with 2 dead clones I had to rezz in the small break (equals FAIL)

I've been able to do a full run at level 49,
you can probably do better then me

Next 2 instance events you'll have to watch out for :
Princess in Maura is nature immune, failed once, I didn't even bother trying again.
The 2 dragons spawning in Sunken after you kill the troll boss are nature Immune aswell,
just line the clones against a wall and melee / shock worked for me.
