I don't understand the reasoning behind this limitation. I have several alts, all of which I play regularly with, but when I try to aquire something like a heirloomed horse for my cav alt, I am unable to do so.
As it stands, there is no possible way to exploit the system. A main character gets heirlooms faster than a gen 1 alt. Aside from archers, all classes have similar gold income.
Is there a chance this restriction will be lifted in the future?
