Guild Wars: Factions FAQ
Before my Factions characters were locked, I was doing the standard PvE unlocking dance. I'm told by one of my guildies that there are no skill quests in Factions after the secondary-profession quests on the Island - but she wasn't 100% sure since she hadn't done all the quests yet. Anyone know for sure?
In any event, it seems like there are very few skill quests - so don't go crazy buying every skill from skill trainers or you'll run out of money. Save the $ for the good skills and leave the trash for later.
Update: according to this thread (warning: potential spoilers!), my co-guildmember (I need a better term here - I hate "guildie"! Suggestions?) is indeed correct. You have to use $ for all the skills after the initial Island and in fact most of the skills at the Island too.
