Having mobs drop the mats you need for crafting is fine in fact its time tested and a great idea, having a very limited amount of mobs that do drop it leads to massive problems.

excluding dungeons as far as i am aware there are a total of 11 mobs in total that drop dirmite web making it a prime place for bot's to camp and even without bot's if there are 4-5 people grinding them for mats the range based dps archer/bard/mage as a massive advantage over melee as they can "tag" the mob before the melee class can get anywhere near it.

it gets even worse when it comes to getting fleece which again as far as im aware only 7-8 mobs drop it and again perma camped by people trying to get the mats

what i am complaining about is the shear lack of mobs that drop critical crafting mats its for this reason the prices for web/fleece/felt are stupidly high the mats sell for more than the end product yet if people dont buy/make them they cant level it.

Its a simple solution add more dam mobs
