I don't normally do this, but I'm kind of in a pickle and I have to make a judgement call. Normally I would just do what feels right (or less wrong) to me personally but I thought this time I'd open it up to discussion :)
The Alchemy discovery system in MoP is kind of weird. Having only gone through the process once, I can't be 100% sure of my findings. I have some theories on the situation but I would need to level Alchemy a few more times to really solidify my data. I can't really do that in the Beta since we are limited to 5 character copies and I need to test other professions.
So what I want to open up for discussion is this: in a world where Alchemy recipes *may* not have a set skill level at which they are unlocked, how would you guys like to see this listed in the recipe chart? On top of this, what if we can't be certain what the lowest possible level is? Right now I'm toying with listing them all at 525. Another option is to list them at the skill level I discovered them in my test (possibly rounding to the nearest 5 point break). The bad part is that none of these options will mirror anyone's actual experience. So I'm not sure about the best way to provide information on these recipes without being misleading or just wrong.
For the record, some of the information on Wowhead is already wrong. I was able to discover 4 of the 5 flask recipes at 525 (they are listed at 550). I believe they built their list before the revamp of Alchemy (to the discovery system) and are showing the older data on the recipes. The color coding they have appears to be correct in the spot checks I've done. But I believe there may be some randomization in the system that allows you to learn recipes that are higher in the difficulty progression. I suspect there's also a cap to how many recipes you can unlock at a given skill level. And I've confirmed that sometimes you won't discover a particular recipe until it's already gray (this happened to me twice).
So what's the best way to label these recipes that so far look to be all over the place in terms of skill level needed to unlock? For Inscription, I listed discovery recipes at the skill level you learned the research recipe for it. I'm not convinced that's applicable here since the discovery process kicks in with the very first recipe you learn from the trainer and seems to apply to all of the other recipes.
