Whinners please note:
Prices have fallen, amounts of ammo crafted in one go have changed, relative value of ore, minerals and alloys have fallen because we have introduced their advanced versions. So 1 ore before the wipe does not equal 1 ore after it.
Looking at the current rate of xp gain.
Before the wipe:
Level 0 - Crafted @ $3k an hour - xp @ 30% of prices = 900 xp an hour
Level 1 - Crafted at $3.3k an hour - xp @ 30% of prices = 990 xp an hour
Level 2 - Crafted at $3.6k an hour - xp @ 30% of prices = 1080 xp an hour
Level 3 - Crafted at $3.9k an hour - xp @ 30% of prices = 1170 xp an hour
After the wipe
Level 0 - Crafts at $2k an hour - xp @ 20% of prices = 400 xp an hour
Level 1 - Crafts at $3k an hour - xp @ 20% of prices = 600 xp an hour
Level 2 - Crafts at $4k an hour - xp @ 20% of prices = 800 xp an hour
Level 3 - Crafts at $5k an hour - xp @ 20% of prices = 1000 xp an hour
What has actually happened is a change to the rate of crafting to differentiate the higher professions crafting speed a bit more (this helped reduce the massive timeouts for the really expensive stuff), the rate of xp has fallen from 30% to 20% (a change which should've happened months ago but couldn't because of incompaitible versions) and many prices have decreased by a lot (so xp from the same item looks a lot less, but it is infact a lot closer percentage wise over an hour)
