No, rogues do not get 2 AP per 1 Agil. Due to the other bonuses of agility (like crit), 1 Agil is often considered equivalent to 2 AP, but that's only a very rough rule of thumb.

Of course there are more enchants. The point of the article is enchants/enhancements that require a profession to use. Anyone can get Armsman, so there's no point in being an enchanter if that's all you want.

"Reticulated Armor Webbing: +800 armor to gloves. This would be applied in place of +15 expertise rating or +35 AP. "

Clearly leaving out an enchant in this statement is incorrect. It wouldn't be applied in place of +35 AP. This is what I meant by missing enchants. The enchants are missing in context.

" Agility is inefficient to everyone except rogues, hunters, shamans and druid cats, who would get +22 AP from it as well as the crit/dodge/armor."

Another misleading statement, as well as being incorrect. For tanks this is largely considered one of the most useful enchants if you don't require the DEF rating. Yet no tank classes are even mentioned.

I chose a few examples to illustrate my point. If you post an article on comparisons, or include math, you should take the time to make sure they are correct. Or stick to writing things that don't require those things. Leaving things out in the context of this article is careless at best.
