you need only one enchanter
I can see no need for multiple enchanters on a single team. just vendor your quest rewards on the alternate characters.
decide which field gives you the best bang for your team like blacksmithing,leatherworking,tailoring, engineering.
I have my pally as BS/mining, one leather/skin, one tailor/enchat, etc.
I've always wanted multiple tailors or special cloth or multiple BS for titansteel.
but I can barely find enough titanium to keep the one BS making titansteel anyway.
