The server is meant to be low-rate, so players are expected to do quests, BHs, FBs and some grinding in order to level up.
X1 rates, however, are too hardcore. We've all played PW already and know most, if not all of the content, so the leveling up process would be naturally tedious.
I suggest the following.
Regular mobs:
XP x1.5, Spirit x1.5, Gold x3
Quest xp
x1 xp&spirit for quests lvl < 30 (there's a lot of them at this point, enough to lvl up)
x1.5 xp&spirit for all higher quests
x5 gold for all quests
Mineable resources:
3-4 logs/ores/stacks per bank
4-6 herbs per plant
There are also additional ways of gaining XP, Spirit, and Coins - check out other concept pages.
