Amaranthian

I would keep mining. My warlock is an enchanter/tailor, and trying to get both to 375 eats up gold at an astonishing rate.

Enchanting used to be profitable (I sold enchants regularly on the AH bridge in IF on Silvermoon for many months), but now even the higher-end enchants are so common that you can't charge much (if anything) for them. When it comes to income, at least with Tailoring you can craft items and sell them in the AH, plus craft BoP items for your own use.

Also frustrating about Enchanting is that most other crafting professions have had some great faction reward recipes added with recent patches, while Enchanting still has little or nothing. For this reason alone, if I hadn't already invested so much time and $$$$ in the profession I would probably switch to something else.

My $0.02.

Enchanting isn't great. It's the quintessential "know an enchanter but don't be one" profession. It's nice to be able to DE things, so for this reason it's good to have an enchanter alt leveled just high enough to be able to DE everything, and use it as a gathering profession, just to get enchanting mats. For your main i'd stick with a true gathering profession.

it depends on what you want, which class you should level. The only class I would say you shouldn't level is a mage. Also hunter, since you already have a high-ish level one. I tend to prefer hybridy-type classes, like druid, shaman, paladin, or warrior, that can fill multiple roles depending on what you want to do.

I agree with Vas. Mages are the shit.

For an alt I think it's important to try and relearn the game so to speak. My main is a rogue so I wanted to see what tanking was like so I rolled a Paladin. I also wanted to wear plate and shields etc. as opposed to leather and daggers. It's good if you can set up a symbiotic relationship between your alts for mats needed for whatever profession you're interested in. My main is Alchemy/Enchanting and my alt Engineering/Herbology. My alt farms the herbs for my pots and my main DE's the gear, engineering is great for mote farming and the BoP goggles are better than t5.

If I were you, I would roll a DPS character that isn't dependent on mana or casting for a change of pace. Try a rogue, warrior, or a feral druid.

Shaman aren't nearly as fun to play until you get DW and water shield. I went entire levels between 60 and 70 w/o ever sitting down to drink because water shield would pretty much keep my mana full. DW + WF is crazy. When I am leveling something I am always a fan of having to mash buttons. The more buttons I have to mash the less I notice the time going by it seems.
