Coilfang reservoir, a goldmine in cata?

Sorry that I haven't posted in a while, have had blogger's block. Ok now onto the topic for today, sanguine hibiscus. These little flowers can be farmed in one of the coilfang resevoir dungeons which I believe is the underbog. Now these flowers are used to gain reputation with the sporeggar reputation in zangarmarsh, there's about 10-15 per dungeon run and you can stealth run or take an 85 and go around collecting these. On my server they're are worth about 8-15g each and it varies almost every other day. I believe these items are recieving some attention from both the buyer's and the seller's eyes because they are easy to obtain and they help with one of the achievements for guild achievements which is get 50 reputations to exalted. The easiest way to obtain these is obviously just doing a run of the underbog without aggroing any mobs, if posssible do it on a toon with herbalism and you can also collect any herbs along the way, I believe that ancient lichen is plentiful in this dungeon. The second item we'll be talking about is coilfang armaments, now unlike sanguine hibiscus these drop off of the mobs in the steam vaults and are used for cenarion expedition reputation in zangarmarsh. On my server the armaments go for about 15g each, maybe a little more. Now the simplest way to obtain these is to do a full clear of steam vaults which for an 85 can take anywhere from 15-30 minutes depending on gear level, spec and class. This can also be a good source of green items for disenchantment for TBC enchanting mats. I urge everyone to try these methods of making gold and to check the prices on your Auction House before going off and doing these dungeons.
I will try to write more blog posts more often and am also taking suggestions on what to write about because I'm here because of you guys and would very much like to hear what all of you would like to read about.
