Hunters vs.... advice

[Valilor]

In some arena's you quite often come one-on-one against some classes and I was wondering how any of you would deal with these scenario's given that you're a SV hunter (no silencing shot) with a Crab:

Hunter vs Lock (esp if there's little LoS options)
Hunter vs Mage
Hunter vs any healer!
Hunter vs Prot Warrior (or whatever the one that charges a lot is)

Get a Ravager instead!
I prefer Ravager big time. It also works better versus casters, which you seem to be having problems with.

Druid?

Druid?

I don't mind druids too much, I get to use my favourite skill on them - scare beast!
