Bet you didn’t see that coming! Actually, believe it or not, herbalism is the ONLY way to obtain volatile life in cataclysm. At one time there were mobs which could be killed very quickly in Hyjal that dropped the volatile life but Blizzard nerfed the farming spot for XP reasons and took away any rewards for killing the plants. Quite a shame actually!
Because only Herbalists can farm volatile life in cataclysm, you probably are wondering which class/race combination you should choose for farming herbs. Believe it or not, a tauren druid is by far the best due to their faster gathering speed by not having to dismount when picking herbs. It doesn’t take long to pay for Azeroth flying (“new old world flying”) by simply gathering up stormvine and whiptail from uldum and twilight highlands.
Having an addon to help with gathering is definitely a bonus, as is having both a miner and herbalist on the same character. This is because you can now see both mining and herb nodes at the same time on the mini map! The addon which helps you gather faster is called Gatherer (surprise!). Its sister addon, Gatherer_mate, contains all the nodes in the game and by installing both and loading up the Gatherer_mate data you can then see all nodes in any zone of any expansion. Pretty helpful huh?
A gold guide will allow you to quickly setup another addon, Routes, which will show you the fastest routes to each node in the zone you’re currently visiting. What’s more, it will show you how best to sell off your materials that you gather and make even more gold (more importantly prevent you from losing it!).
