I've played on several private servers, but this is by far the worst as far as cloth drops go. Mining, you see the nodes you mine the nodes... Herbalism, you see the herb, you pick the herb.. skinning... you kill a beast and skin it.. every beast has a skin, every mining node has an ore and every herb node has an herb..Humanoids are supposed to drop cloth (since they wear clothing?) however, it seems 90% of humanoid mobs are nudists. There is a bottle neck at both mageweave and more so at rune cloth. Now I don't mind killing 2 or 3 mobs to get a couple rune cloth, but when you have to kill 10 to 15 for a single bit of cloth, that is ridiculous!
Most private servers refer to wowhead for which mobs drop which items, or archived posts, apparently warmane refers to cavernsoftime, but that is a lich king database, utterly worthless (or very inaccurate) for BC farming purposes.
Now just to prove that I am not whining here, I suggest warmane staff actually level tailoring, on a new character (no fair killing lev 5 kobolds on your 70 paladin)
Not only is this cloth shortage affecting tailoring, it is also affecting enchanting, since most enchanters are tailors, and enchanting mats mostly come from drops and crafted items.
