Just started playing on this server today and I'm confused about the low level progression with the boosted XP.
I started as undead and quickly reached level 10 with the deathknell quests and I can't find any quests now that have boosted XP. I headed to Silverpine only to find a lack of quests there as well.
How am I meant to progress on this server?
Check your minimap for the 'tracking' button, and select "Low level quests" to show up. This way, even if you're over-levelled for a certain location, you can still do their quests for the exp and gold.
Otherwise, yeah, you can just move on to the higher level locations.
