i was actually thinking about power leveling all of the gathering professions across my toons-- could make some mad golds just farming an entire zone for crafting mats.
i don't really know what JC daily you're referring to, i haven't looked into it... but would it really be very productive to power level one profession on 5 different toons? though i suppose you could actually have all of them be JC's AND a gathering prof if you wanted...
