well thats not going to be an issue because if i recall the max damage bonus is only going to be like 1d4... its not going to be anything move powerful than whats already out, its advantage is going to be its customization and thats about it
and 10 wands is nothing, most of my toons have about 10 wands and my hin has like a bit over 20
A crafting system that is not balanced with its other content is going to cause problems, yes. But craft systems can equally work well with the other content. It's all in the details and thus ultimately the hands of our admin, who I'd be inclined to trust on the matter.
A system may allow you to craft base items from custom materials, weapons, armour and all manner of miscellaneous, as far as RP items and placeable props, magical inks, bottles, food and drinks, the list is huge. None of the crafted items need have significant instrinsic properties, they are items that may have varying enchantments put on them by a separate enchanting system.
Permanent enchantments are not likely to be as powerful as temporary ones, preserving the place of the skilled caster. The scope of those enchantments may not be so broad as to undermine the random loot, which may remain a source of unusual item properties.
Care needs be taken in many places, particularly in the enchantment cost system outlined by the existing spells. We may wish to be able to augment those random items as well as the crafted ones, but need to ensure that epic and grandafthered items do not produce any power creep.
