sell whatever you don't need. if it can be sold on the AH, sell it there as you will make more money than vendoring it. do check from time to time what can be sold on the AH. if you are unsure of what prices to put, search for that items and list it according to what the average is on the AH.

don't wait til you are level 35 to start saving for mount. start from the very beginning. that way you don't have to waste time farming but can spend that time on grinding. i didn't spend my money on anything and when i reached level 40, i had around 110g. and i was power leveling.

btw INFeRNO, you talking from the POV of a mage i suppose. not everybody plays mages and can AOE.

people talking about level 40 mount you go talk bout Tyr's hand pulak. lol.

IMO, of all 3 of the gathering professions herbalism makes the most. you can get herbs anywhere and everywhere as opposed to running along mountains & hills to look for mineral nodes. the respawn rate is the same as mining but they are much more abundant and sell faster than minerals. early levels won't sell but you can use those herbs to level your alchemy, if you took that profession up as well.
when both alchemy and herbalism are 300, both can sell well on the AH. you just have to know what is in demand to be able to make money.

70g per living essence? you've got to be kidding me!! of the 3 servers i've played on, i've never seen it sell more than 10g!

mining doesn't sell as fast because the stuff you craft with the minerals can't be re-used, they only craft 1 of them. but people keep making pots and using them. so there is more demand for herbalism.

if you don't plan on taking up enchanting (as in continuing to level it to 300), then don't pick it up. make an alt, level it to level 5 and go learn enchanting just to disenchant stuff. send what ever greens or blue you don't want to your alt to be disenchanted. then you can either AH those stuff of or keep them to get enchant for your main.

SnoWFisH: your server is really screwed. 65g for an arcane crystal. lol. i never seen more than 30g before. but Eye of Shadow is still quite reasonable. on my server it goes for around 800g, and my server is farmers server.

wh'yd you donate silk? should've sold it. plan ahead for epics!!

but it is hard to level a pally.

but you are going to suffer when you want your epic mount. the epic mount for Palladins and Warlocks actually costs more than a normal epic mount. also takes up more time to obtain 1 then a normal epic mount.
