Miner's sell ingots so that other players can gain tink and smithing. It's not the same for taming. Just because another player has GM smithing or GM tink doesn't mean that you can't smith a set of armor or make an assembly. For taming, once there are loads of GM tamers then each tamer has less of a chance of doing what they do as tamers; TAMING! Therefore, you can't put taming and smithing in the same sentence :/. You're comparing apples and oranges.

Again, this is exactly my point. People are deliberately hindered from gaining skill by some other players because it is in those players best interest to stop anyone else gaining skill because of the mechanics of how rares spawn. Any ideas about how to do something about this? Or do you like it how it is? If so why? I'd like to hear your actual thoughts on this. So far you've just laughed at some people for selling stangs and given multiple choice questions c'mon rabs, helpful input please ;D

edit: Thinking on it, you did raise a good point about how stangs move through the market, mounts being passed back and fourth between several tamers so they all gain skill for relatively cheap. If something similar to what I suggested ever happens, there would have to be a change to that, like you can only gain skill first tame, or maybe two tames per ride instead of 5. But of course with my idea they wouldnt be forced to buy them, they can look for um and actually find one in less then 100 hours of searching. It just sorta seems silly to me to be macroing taming on a few rides in your house. A tamer should be out in the wilds gaining skill dont ya think? Setting a limit to 2 would mean only the original tamer is going to be able to profit off selling it for skillgain, if they chose to sell it. But why wouldn't they? They wouldn't be in direct competition over the resource. The rarity of the rides and thus their value would come from three things, the difficulty of finding the spawn, length of the timers set by staff, and if its not a world spawn then the difficulty of the encounter to get it. Not by how many hundreds of every type of ride a tamer can stash away from the market in his bank so as not to allow any other tamers to gain skill. Thats a falsely inflated market by a player injecting scarcity. Anyone should be able to collect many hundreds of mounts, if thats their goal, but theres no reason it should be at the expense of everyone else.

only one of these is a rival in consumption, d, which fits the definition. That's why it was bolded .

Yes believe it or not I picked up on that, what I was pointing out was all 4 actually fit with our current system. Lets have a look again.

people can be prevented from using the good(spawn) - Obviously true.
everyone will be excluded from obtaining the good - True (Although not completely, but semantics aside, true)
no more than one person can use the good at the same time - True (I'm of course applying this rule to an individual spawn, once one person tames from it, no one else can)
one person's use of the good diminishes another person's ability to use it - Again obviously true.
