Least valuable Gathering profession INSIDE Dungeons?

[nodoze]

What do people consider the least valuable Gathering profession INSIDE the Classic WoW end-game Dungeons?

If you were to Rank them would rank them Mining > Skinning > Herbalism for their value inside Dungeons?

From memory Mining is critical for Dark Iron ore among other things.

I remember Skinning tons of mobs in Vanilla but don't know if skinning is important inside the end game instances we would be otherwise regularly farming for gold.

I think some things may leverage herbalism in dungeons but I don't know if the particular herbs available are only available in abundance inside an instance (like Dark Iron ore) &/or if the quantity of them warrants a proficiency slot over mining or Skinning.

The reason I ask is because I am planning the following proficiencies while leveling:

Character1.Character2.Character3.Character4.Character5;
Enchanting.Enchanting.Enchanting.Enchanting.Enchanting;
Nothing....Nothing....Mining.....Skinning...Herbalism;

Note: I was planning on basic Enchanting on each character while leveling to disenchant bound gear that each character outlevels. Once I get most into BiS gear and start prepping for PVP I plan to just keep one Enchanter in the party...

And then at cap, for PVP, I am planning the following proficiencies:

Character1.Character2.Character3.Character4.Character5;
Engineer...Engineer...Engineer...Engineer...Enchanting;
BlackSmith.BlackSmith.Mining.....Skinning...Engineer;

Basically to fit in the things I want for PVP on my main group I can only keep 2 gathering proficiencies... When not PVPing my team will likely be grinding instances so keeping some Gathering may make sense... My assumption up to now was that I would drop Herbalism but curious which Gathering proficiency others would drop. I do want to keep 1 enchanter in my party to disenchant BoP items that my party can't use and because I don't have a warlock in my party to be able to send a member back to town to a bank alt disenchanter.

Edit2: Note that I plan to have multiple alts not on my main team that can get any proficiencies I want that I can't keep on my main team. I could maybe park one outside a given instance to come in an gather herbs (or whatever) if that made sense...
