I have had a lot of flak from player who have received prayer exp from trying out the new firemaking update, did it actually say anywhere that making incense burners would give prayer? If this was not made clear should they be offer a reset on prayer?
It did surprise me to see I was gaining Prayer experience, but after thinking about it it does make sense considering we are using ashes. (Plus the fact that incense is commonly used in religious type things)
As with any new content though... players who have chosen to limit their gameplay (skillers, pures.. whatever else there is) should know by now to wait before trying out new content, or at the very least take some caution when trying it.
