newbie leveling help/shaman advice

[Roth]

Hi, I really have a two part question but it's interrelated. I'm a level 16 soon to be 17 shaman in mostly banded warmor with a poison wind censor that was given to me. I'm duoing with my gf who is a 15 wizard. The problem I'm seeing is that as I level it's getting way harder to meelee even dark blues and live. My question as far as this is, at what point does it get easier or does it?

Now the next part which is the main question is say I can't really solo anymore as a shaman efficiently after a certain point... where do I go? I tried /whoing to see where people are but it seems like everyone is all over the place. What's a good path to group to 50 or 60?
