I've never played a BA, but from past experience and when helping others I know the Weaver is a fairly hard class to actually get into. Weavers generally aren't wanted in raids, or in number anyway, but BAs are with hinder, burst DPS and what not.
Between Weaver and Warg, Warg is the better starter class. They get stealth at r0 and can move in said stealth. Weavers don't get their immobile stealth skill until r6, or if you buy it from the store early.
