I have 2 alts and I can either go pure herb, pure mining, make herbs into cards/glyphs or make ore into gems.
Just to give you a reference average prices, on my server mining seams average competition and herbing almost zero.
Stack of 'bad' herbs - 15-16g
Stack of 'good' herbs - 17-20g
Stack on ink of the sea - 25-27g
Snowfall ink - 12-13g
Frost lotus - 50g
Stack of saronite ore - 15g
Stack of titanium - 240g
Scarlet ruby - 42g
Cardinal ruby - 150g
Which one do you think would get me the most profit?
