I got an interesting Question from Shayline the other day:
How can I make money with mining and only a limited time to play?
Well this is a very interesting question and one that is a real problem for the casual player.
First off all: you have 2 proffesion slots: so take another one with you (a crafting one)
But about the mining now:
1st of all: get to know whats high priced in the server and what can be sold in large quantities.
Since your on my own server, mithril and saronite are both good for their time.
2nd off all: try to get to an agreement with someone that they will buy lets say 5-10 stacks from you, every week for a fixed price. That way you are sure of income.
3th: if you can't get someone to keep buying your stuff: AH.. never ever sell something that can be used to a vendor.. always to a real player, either by /2 or AH.
Since mining is a gather proffesion, you'll always have to spend time to gather which means you can't make more money then the time put in. Ofc if you are grinding for mines in scholozar basin, you can get up to 450-600G for an hour of farming. which is significantly lower than what I make for 30mins at AH.
What could also boost your income with mining:
Get someone to prospect your ore, and sell the gems instead, and see if it's worthwile it.
My recommendation for "casual" players: Get some money together, then drop the gathering proffesion and level jewelcrafting or inscription. You'll earn double the money with only half the effort!
