Cash shop skillbooks (KMS)

Quotes from spadow
"The mastery books in Cash Shop actually give you one extra SP. So when I use a mastery book on 10 Sudden Raid, I will have 11 in Sudden Raid."

does rhat mean using cs books will give you extra skillpoints?! :o permanently?! What about people who allready used the regular books? They will end up with less sp at lvl 200? Can somebody give me more info on this ..

Thanks,

Exactly as you state, the ones using CS-books will get an extra skillpoint more per book, permanently over others. That is, as long they get the same amount of skillpoints from weapons, equips, etc.

Meaning people who used a regular skillbook, or old classes in case they get cs skillbooks, have a permanent disadvantage..

I almost wish there was a gene 30 skill book so I could finish my bishop :/
