For some reason cheese making's requirements for stomachs have given a sort of jokey 'endgame' reputation. A bit like the equally bizarre and kind of silly Poetry Appreciation is, cheese making is essentially a weird way to brag about how uber one is, to talk about the grind of CM, and how far along you are in it. The truth is it is super easy to level if you have a fuck ton of gold, as you just buy stomachs, and then level, simply wasting thousands of gold on the way. Which of course is of no consequence do to the bizarre way we are getting a cash wipe, but not a skill wipe. That fact simply encourages it.

Your suggestions are good - stomachs should be less rare or perhaps 1 stomach could be used to make 10 rennet. Whatever the solution, needing masses of stomachs is just a bit silly for the role cheese making fills in game.

Also, sorry about the high levels taking the mobs. I guess it is just a bit of a design flaw at the moment that people level 70 can farm level 25 mobs for loot. Would be better if they greyed out and became non-aggro, non-loot.
