So I'm trying to word this right here,

I've done one of my pvp alts first, and done every quest in 4 zones and some in the dread waste, next I'm doing my main, now on him, I want to level via questing, but I want to do dungeons more than once, and some pvp, (which I didnt do on my alt incase I missed something important) after him I have 6 more to level,

What I want to know, is, do I need to do every single quest on each one of them to have "everything" unlocked that a 90 alt needs, and if so which ones?
