Stat Weights on Botany

[Marka]

I've just acquired my full Botany gear set and was wondering if theres a certain stat we would prefer over the other in terms of attaching materias to gear. Perception affects HQ rate, will additional GP be better?

That depends entirely on what you want to do with it...

Gathering will increase your success rate (note: Unspoiled caps at 90% [95% for clusters])
Perception will increase your HQ rate (note: You'll need at least 320 to gather HQs out of Unspoiled Nodes)
GP will increase the amount of abilities you can use at any single node.

What you need or want will entirely depend on what you prefer. Personally, I got my Gathering to the 90% threshold (340ish), I got my Perception to 320, pushed my GP to 585, and then just left it alone. Beyond that, I didn't care to add anything, so half of my AF (and my offhand) don't have any melds at all.
