Guild Wars 2

Q1: Will we still be able to get the random daily drops of black lion salvage kits and mystic forge stones etc. (Will this be rewarded in the daily login or is it completely removed from drops now)
Q2: Will the PVP achievements be account based like for instance if I only have a mesmer guardian ele warrior and engi as my characters classes will I only get the win match with x class with those classes or will it lock players out from obtaining the win a match with x class daily achievement?
Q3: By legendary crafting materials does that include precursors ?

Achievements have always been account base, and based on arenanets track record rewards always turn out to be very lacking so I seriously doubt legendary crafting materials will contain precursors.
