Struggling Troll Shaman.

[DustDevil68]

So, Ive started up a troll shaman and have made it to lvl 6, but its been a huge struggle the entire way. I'm at the point that I'm starting to think I'll stop playing him, but i really like the spells that the get later and really dont want to stop. What weapons should I be using to melee mobs down, as well as, spell combo's at this lvl. Is it really this rough early in the game at this lvl and I just need to power through it? Help, please.
