GMS v109 - Alliance Eternal

OK, what? The difference between 11 and 1 is also cheaper MP wise, and AFAIK weapon speed gets increased by one (Unless you're thinking of KMS.)

And what do you mean by that? Are the Vipers rare? Has people given up on Buccaneers becoming Vipers because of how hard it is to train as a 3rd jobber? If that's the case, then Strikers are the best bet for Wind Booster Mule.

Ever since Big Bang hit, Wind Booster has retained the -2 attack speed effect at level 1. There's no reason to level it beyond level 1 except for buff duration.

Phantoms won't need need the skill at all. Why would they take something they don't really need?
