I would say because it's a Time Locked progression server, and bonus XP only encourages racing to the max level to then complain about there being nothing to do.
All Access Members on all servers got the bonuses - double currency and double tradeskill experience from quests.
I think there were two big issues: Most people thought it was "Double Tradeskill Experience," not "Double Tradeskill Experience from Quests." Most people aren't sure what counts as a tradeskill quest (i.e. do writs count?).
Do they? Writs used to be considered missions not quests and a lot of people reported that they were not getting 2X xp from writs.
I got and everyone I talk to got 2x exp from writs, so dunno. What is the different between missions and quests mechanics wise?
