I would suggest making sure one of your chars in an enchanter/tailor for bops disenchants. I spend alot of time camping shards at 70, and this will save you alot of gold in the long run.

Alchemy and jewel crafting are all huge money sinks. If you have the patience, do it up front and dont make yourself go back and work it up.

Enchants, gems, and their corresponding primals will cost you so much for 5 chars.

If you need any help with macros, strats or anything else. Please feel free to send me a message or email.
