I'm trying to use writs and master writs to help level subclassing skill lines, but regular writs are doing pretty darn slowly to say the least. Master writs, on the other hand, for sure are a good way to speed level subclassing skill lines, as is turning in quests in Cyrodiil and other significant PvE quests. But I'm a PvP main, so re-running redundant PvE content is not my prefererance.
My main question is does having an XP scroll or potion active while doing normal daily writs inclrease the XP and thus the leveling of the subclassing skill line? Or is the XP potion/scroll irrelevant to how much leveling will happen with the subclassing skill line while doin normal daily writs? Is the bonus, if there is one, the same for when we do master writs for leveling subclassing?
I've already got the few subclassing lines I deemed most important knocked out, but I don't want to grind out the rest of them the same way. I'm not in a hurry for the rest, so I'd like to know the most efficient way to level subclassing skill lines using plain daily writs. Do the XP bonuses help the leveling of subclassing using normal daily writs or not?
And finally, would a double XP event help us speed level subclassing using writs or not?
TIA
