X-Pots of Strength

[Sapphic]

Why the discrepency in materials required for X-pots of stat?

Dex pot--Dart frog. A level 45 botany harvest
Vit pot--Grenade ash. A level 40 Mining harvest. Can get from miner retainer
Int pot--Black Scorpion. A level 42 botany harvest
Mnd pot--Pudding flesh, A little harder to get due to limited puddings available in world. Can get 10/ hour from hunting ventures

I don't have a Botany retainer, so if someone can check if Black scorpion and Dart frog are available as ventures I'll edit in.

All easy to get, single items required to craft respective X-potions.

Then there's X-Pot of Str, not only does it require 2 items, Silver shark and hammerhead shark one being a mooch the other a straight cast, but also an additional craft to make the Shark oil. Which is not available from ventures. One type of shark is.

Making STR pots more of a pain to make than the others, any reasons why?

nb. I'm not saying they are difficult to make, just the amount of time/gil you have to put in to make them compared to the others is unbalanced.

Solution? Make them require only one of the sharks to bring them to the same level as the other pots. The shark (I forget which) which is available through ventures also,
