Ebonweave, spellweave and moonshroud are good sellers now due to patterns like Merlin's robe - but there's no guarantee that market will hold up over time, and honestly, the 4 day cooldown is ridiculous, not to mention the cost of the cloth itself. If you want to make a lot of money, there are better ways than tailoring cooldowns.

Icy Prisms are a waste of frozen orbs, IMHO. I think I made one.

JC is nice because it has a daily thats easy to do, and lets you buy the higher quality cuts and jewelry.

Alch is a money maker now, without needing stacks of Frozen Lotus. I epic gem a day, plus unlimited titanium transmutes, and flasks.

Mining is going to be tough on 5, ore nodes are in high demand, and it's hard enough on one. I would'nt want to level 5 miners, and you can't buy your way to 450.
