But... they have class requirements. Or does it convert to the other class if sending it to another legacy char.
And even if so, your teammates can't wear them then...
EDIT (to above post appearing when I was typing this);
Don't see the profit. You can just send the enchantments itself no? Would be cheaper than putting it in Legacy gear and extracting them afterwards, since that costs (again) extraction costs. Which get expensive with high-tier enhancements.
