I understand your previous answer, and I’m sure you are answering a question I am not asking.
You said:
“If you WoD mining is at 43, that has no relation to whether you can mine Saronite Ore (a WotLK material).”
That is my understanding, and it is exactly why I am asking my question. What it tells me is even if I have 100 BfA mining, I cannot tell by looking at my skill level alone whether or not I can mine or craft X. I must also know what my skill level is for that expansion see? That means that as I was asking before, I will need to track the skill level for each expansion?
I just don’t see how I can look at one number and know whether I have a high enough skill level for any given plan or node gathering. I can’t break it out, all in my head, which alt has done what. I have far too many alts and professions to keep track of what I learned where and when, so the idea of “if I learned X before or after xpac or if my skill level was X before or after BfA” then the answer is yes/no… that is just too much.
So it definitely sounds as I was saying in my first post, I now have 88 skill level numbers to keep track of on my spreadsheet.
Unless you are saying: “Once you have learned the base skill, then you have a high enough skill to learn/farm any plan/resource for that expansion.” Is that what you are saying? e.g., If I train the base level tailoring for classic, then I am high enough at that point to craft Onyxia Hide Cloak? Which was certainly not a base level crafting skill back in Classic.
If that is true then I only need to track yes/no for each skill for each expansion, but it is still a lot to keep track of. Otherwise, just by looking at my single skill number, I cannot know:
Is my engineering alt high enough to learn Mekgineers chopper? I have to know the skill level for that particular expansion. The base skill level for that expansion was not high enough to learn those plans.
I think the part that you are missing in my question is not “can I get to it?” which I understand may or may not involve skill leveling; I am not asking anything along those lines. I want to know “am I there already?” is what I am asking. And I mean just by looking at my spreadsheet, and not having to do the problem solving all over to remember did I level this one before or after xpac, and what level was it?
I may be on one toon, and need to know if another alt is currently high enough to… do X. -without logging out and logging into the alt to check if I have the plans or w/e. I want to know right now, quickly. How am I supposed to do that without knowing the skill level for each trade, for each expansion, and without trying to remember, whether I leveled it before the expansion, which expansion, what level was the char at the time and what level was the skill at the time.
